Real-World Inputs and Outputs

Overview

Reading and writing to Excel Making controlled PDFs Submitting commands to Windows Sending email Inputs from the Web

Outputting to Excel

Typical Scenario:Need to design a report from SAS datasets to be read by regular analysts in Excel.

Typical Solution:SAS dataset is ‘Exported’ either as an Excel file, or as a comma delimited file.

Outputting to Excel

Problem:

PROC EXPORT DATA= SASHELP.Tourism OUTFILE= "C:\output.xls" DBMS=EXCEL REPLACE; SHEET="sheet1"; RUN;

UGLY!

Dynamic Data Exchange

We can use Dynamic Data Exchange (DDE) to read and write directly to Excel.

Uses X4ML to instruct Excel Can read/write to individual cells or

ranges Can apply formatting to cells Can use conditional formatting and output

Desired Excel Output

Some code for starting DDE

Open Excel for writing:options noxsync noxwait xmin;filename sas2xl dde 'excel|system';data _null_;

length fid rc start stop time 8;fid=fopen('sas2xl','s');if(fid le 0) then do; rc=system('start excel'); start=datetime(); stop=start+10; do while(fid le 0); fid=fopen('sas2xl','s'); time=datetime(); if(time ge stop) then fid=1; end;

end;rc=fclose(fid);

run;

Set up new workbook:/* Get rid of old workbook and *//* create new one. Save it. */%let path = C:\SUNZ;%let name = My workbook;data _null_;

file sas2xl;put '[file.close(false)]';put '[new(1)]';put '[error(false)]';put "[save.as(""&path\&name"")]";

run;

DDE – putting values in cells

filename recrange dde "excel|[My workbook.xls]Sheet1!r2c2:r3c6" notab;

%let t = '09'x;data _null_;

file recrange;put &t &t 'Holidays in Spain' &t 'UK real personal' &t &t 'The consumer price';output;put 'Year' &t &t 'by US residents' &t 'disposable income' &t 'The UK population' &t 'index in Spain';output;

run;

filename recrange clear;

Set a range

Write values toThe range

Clear the range

DDE – putting values in cells

filename recrange dde "excel|[My workbook.xls]Sheet1!r4c2:r13c7" notab;

data _null_;set sashelp.tourism(obs=10);file recrange;put year &t &t vsp &t pdi &t pop &t cpisp;

run;

filename recrange clear;

Set a range

Write values toThe range

Clear the range

DDE – formatting

Submit commands in data steps calling ‘sas2xl’

Zoom to 85%data _null_;

file sas2xl;put '[zoom(85)]';

run;

DDE - formatting

Make headings bold and purple:data _null_;

file sas2xl;put '[select("r2:r3")]';put '[format.font("Arial",10,true,false,false,

false,17,false,false)]';run;

Functions are X4ML functions

Complete help can be found in MACROFUN.hlp… go to:

http://www.microsoft.com/learning/And search for MACROFUN.EXE

Eg: FORMAT.FONT(name_text, size_num, bold, italic, underline, strike, color, outline, shadow)

http://www.microsoft.com/learning/

DDE - formatting

data _null_;file sas2xl;

/* Set background colors */put "[select(""r2c2:r3c2,r2c4:r3c7"")]";put "[patterns(1,0,1)]";put "[select(""r4c2:r13c2"")]";put "[patterns(1,0,39)]";put "[select(""r4c4:r13c7"")]";put "[patterns(1,0,43)]";

/* Set number formats */put '[select("c4,c6")]';put '[format.number("0.00")]';put '[select("c7")]';put '[format.number("0.0000")]';

/* Center all cells */put '[select("c2:c7")]';put '[alignment(3)]';

run;

data _null_;file sas2xl;

/* Set column widths */put '[column.width(7.14,"c2",false)]';put '[column.width(2,"c1,c3",false)]';put '[column.width(18.2,"c4:c7",false)]';

/* Set outlines borders */put '[select("r2c2:r13c2,r2c4:r13c7")]';put '[border(2)]';

/* Set internal borders */put '[select("r2c4:r13c6")]';put '[border(,,1)]';

/* Save and close the file */put '[error(false)]';put '[save]';put '[file.close(false)]';put '[quit()]';

run;

Finished output

DDE – reading Excel sheets

DDE can also be used to read specified ranges from Excel sheets.

data _null_; file sas2xl; put '[file.close(false)]'; put '[open("C:\My workbook")]'; put '[workbook.activate("Sheet1")]';run;

filename recrange dde "excel|[My workbook.xls]Sheet1!r6c4:r8c5" notab;data workbook; infile recrange delimiter='09'x lrecl=1000; input VAR1 $ VAR2 $;run;filename recrange clear;

First open Excel as earlier, and close it again at the end.

Making PDFs

Often, it’s necessary to make a document in PDF format that looks exactly like you want it to.

Example: The invoice for the conference

Making PDFs – proc ganno

Create a dataset with one observation for each item on the PDF.Text entries: function='label'; x=5; y=94.25; style = '"Arial"'; position = '6'; size=3; text='SUNZ'; output;


Drawing lines: function='move'; x=1; y=87; output; function='draw'; x=95; y=87; color = 'black'; line = 1; size=8; output;

Move cursor to start of line

Draw line to finishing position


Finally, invoke the ODS PDF output destination. ods listing close; ods pdf bookmarklist=none file="C:\invoice.pdf";

goptions hpos=100 vpos=100; proc ganno annotate=annodata; run; quit; ods pdf close;

• PROC GANNO very powerful, used for assembling graphs one element at a time, or customising graphs

• Requires SAS/GRAPH

Making PDFs – proc report

No SAS/GRAPH… need to use PROC REPORTHarder!

Approach: • Activate ODS PDF output destination• Call PROC REPORT to place elements on

pageProblems:• PROC REPORT is hard to customise the

appearance of• SAS help is almost useless


•Biggest resource is the paper by Brian T. Schellenberger at SAS

•This paper is written entirely using PROC REPORT and ODS

•Found at http://support.sas.com/rnd/base/topics/odsprinter/qual.pdf


options topmargin=1.25 bottommargin=0.3 leftmargin=0.75 rightmargin=0.75 papersize=a4;

ods path work.templat(update) sasusr.templat(update) sashelp.tmplmst(read);

proc template;define Style styles.format; parent = styles.Printer;replace fonts /

"docFont" = ("Arial", 10pt) "headingFont" = ("Arial", 10pt,bold) "headingEmphasisFont" = ("Arial", 10pt,bold italic) "FixedFont" = ("Courier New, Courier",8pt) "FixedHeadingFont" = ("Courier New, Courier",8pt,bold) "FixedStrongFont" = ("Courier New, Courier",8pt,bold) "FixedEmphasisFont" = ("Courier New, Courier",8pt,italic) "EmphasisFont" = ("Arial", 10pt) "StrongFont" = ("Arial", 8pt, bold) "TitleFont" = ("Arial", 8pt) "TitleFont2" = ("Arial", 8pt)

;end;

run;

First steps: Set some options and define a new style template


Activate the ODS PDF destination: ods listing close; ods printer style=format columns=1 pdf notoc

file="C:\sample.pdf";

options cardimage nodate nonumber; ods escapechar = '\'; ods printer startpage=no;

title; footnote;


Construct a dataset that contains the information you wish to output. Then call PROC REPORT. data text; text = 'This is the line of text we wish to display.'; run;

proc report data=text nowindows noheader style={rules=none frame=void just=l cellspacing=0 cellpadding=0}; define text / style=data; run; quit;

This will output a normal looking line of text


Make macros! %macro standardtext(text);

data text; length text $9999; text = resolve(&text); run;

proc report data=text nowindows noheader style={rules=none frame=void just=l cellspacing=0 cellpadding=0}; define text / style=data; run; quit;

%mend standardtext;

%standardtext("This is the line of text we wish to display.");


Changing appearance of output:• Use escape character ‘\’• To get This is italic

Use %standardtext("This is \S={font_style=italic}italic\S={}");• Some style modifiers are: font_face,

font_size, font_style, font_weight• Can also use shading and borders in the

report table

Note on manipulating files

• Any commands you can execute from the command prompt you can execute with SAS:

• Delete a filesystask command "del C:\sample.pdf" taskname=del;waitfor del;

• Rename a filesystask command "rename C:\sample.pdf letter.pdf" taskname=ren;waitfor ren;

• Run a Word macrosystask command " start /wait /min winword.exe ""C:\mydoc.doc"" /mymacro " taskname=runmacro;waitfor runmacro;

Sending Email using SAS

Add the following lines to your SAS config file (default - C:\Program Files\SAS\SAS9.1\nls\en\SASV9.CFG) -emailsys SMTP -emailhost 'smtp.offlode.com' -emailid '[email protected]'

Then:data _null_; file myemail; put 'Dear David'; put ' '; put 'Thank you for your patience ' @; put 'in sitting through these talks.'; put ' '; put 'Please find attached a PDF'; put ' '; put 'David Woods';run;

filename myemail email to = ("[email protected]") from = "David Woods

<[email protected]>" subject = "Have a nice day" attach = "C:\sample.pdf";

Getting stuff from the web

• Define a webpage as a fileref• Load the HTML source code into a dataset• Search through the dataset to find the

required info

filename webpage url "http://www.nzx.com/";

data nzx; infile webpage length=len lrecl=4000; input htmlline $varying4000. len;

run;

NZX share prices

Examine the source code to find some string which characterizes your target information, then extract the desired info into a new variable.

Google celebrity search

%let firnam = David;%let surnam = Woods;

filename webpage url "http://www.google.co.nz/search?hl=en&q=%22&firnam+&surnam%22&btnG=Google+Search&meta=";

data _null_;infile webpage length=len lrecl=4000;input htmlline $varying4000. len;if index(htmlline,'table width')>0 AND index(htmlline,' of about ')>0 then do; call symput('number',substr(substr(htmlline,index(htmlline,

' of about ')+17),1,index(substr(htmlline,index(htmlline, ' of about ')+17),'<')-1)); stop;end;

run;


Can rank people by celebrity status:

Application for detection of false names, if count is above a certain threshold they might be fake.
