• General Purpose Data Utilities– For Unix, Linux, or Windows

• Replacements for Mainframe Utilities– SORT/SYNCSORT replaced by uvsort

– IEBGENER/IDCAMS replaced by uvcp

www.uvsoftware.ca

5 Parts to Conversion

1. JCL conversion to Korn shell scripts

2. COBOL porting to Micro Focus

3. Data conversion EBCDIC to ASCII

4. VU Testing & Debugging Aids

5. Mainframe Data Utility Replacements

www.uvsoftware.ca

JCL Conversion - Highlights

• DDN/DSN converted to Export DDN=DSN• SORT/SYNCSORT converted to ‘uvsort’• IEBGENER/IDCAMS converted to ‘uvcp’• GDG files converted to ksh functions• Console logging• Micro Focus COBOL animation made easy• Replacements for Ditto, Dyl280, Easytrieve• $RUNDATA/$RUNLIBS testing/production• Laser scripts, 132 cols x 66 lines on 8½ x 11

Notes re Hyperlinked Samples

• Hyperlinked samples begin on next slide– Click hyperlinks (Red) to view sample files

– Returning to slide depends on your browser

• IE – use your back button, do not kill– IE displays both PPT & HTML samples

• FireFox – kill the browser (X)– Firefox downloads PPT to run on your desktop

– And honors the hyperlinks to samples on web

JCL Conversion Example #1

• sample JCL & script (1 step COBOL)

• Korn shell script equivalent

www.uvsoftware.ca

JCL Conversion Ex#2 (SORT)

• Sample SORT conversion to uvsort

- original mainframe SORT step

- equivalent uvsort in ksh script

www.uvsoftware.ca

SyncSort conversion to uvsort

• Syncsort functionality at lower cost• INCLUDEs,OMITs,SUMs,OUTREC,etc.• Uvsort sels, dels, sums, mvcs, etc.• sample INCLUDE AND/OR conditions

www.uvsoftware.ca

JCL Conversion #3 (GDG files)

• GDG files supported by ksh functions• exportgen0, exportgen1, exportgenp• sample JCL & script with GDG files

www.uvsoftware.ca

IEBGENER & IDCAMS

• IEBGENER converted to ‘uvcp’• IDCAMS REPRO converted to ‘uvcp’• IEBGENER & IDCAMS JCL sample• Korn shell script equivalent

www.uvsoftware.ca

COBOL porting to Micro Focus• Not much to do, but saves manual editing

• Insert EXTERNAL on select/assign stmts

• Translate to lower case except in quotes– more modern appearance

– easier to edit with unix/linux editors (vi,etc)

• Insert detail file status test code– For Micro Focus extended file status display

www.uvsoftware.ca

Data Conversion

• Translate EBCDIC to ASCII– Preserving packed/binary fields

– Correcting zoned signs to ASCII standards

• Conversion jobs generated from copybooks– and LISTCAT file specs

• 1 script to generate all conversion jobs• 1 command to convert all data files

www.uvsoftware.ca

Data Conversion Example

• Conversions generated from copybooks Sample copybook (citytax1.cpy)

• CobMap record layout from copybook Sample cobmap (citytax.map)

• Data conversion job (uvcopy) Sample uvcopy data conversion (citytax1.uv)

www.uvsoftware.ca

Data File specs from LISTCAT

• LISTCAT info completes conversions– added to copybook/cobmap/uvcopy job

– Data filename, file type, Indexed keys

Sample LISTCAT & extracted control file

uvcopy job completed by control file

www.uvsoftware.ca

Converting files for RDBMS

• Convert data to pipe delimited text files– Packed/binary fields edited signs & decimals

• Packed/binary fields unpacked & edited– Conversion jobs auto-gen’d from copybooks

• SQL loader control file also generated

• Sample pipe delimited output file

• Sample uvcopy job to perform pipe delimit

• Sample loader control file

www.uvsoftware.ca

Conversion Directories

• For JCL,COBOL,& Data conversions• Conversion Libraries

• Data directories for testing or production• sample test data subdirs

www.uvsoftware.ca

Scripts convert All JCL/COBOL/DATA

• jcl2ksh5A – convert All JCL to ksh

• cnvMF5A – convert all COBOL to Micro Focus

• gencnvC - generate all Data conversion jobs

• uvcopyxx pfx2/* - execute all data convert jobs

www.uvsoftware.ca

Scripts to convert 1 JCL/COBOL/DataFile

• jcl2ksh51 – convert 1 JCL to ksh• cnvMF51 – convert 1 program to MicroFocus

• gencnvB – convert 1 datafile to ASCII• genpipeA – convert 1 file to pipe-delimited

• uvcopy pfx3/datafilename – execute 1 conversion job

www.uvsoftware.ca

Testing & Debugging Aids

• uvhd & uvhdcob – data file investigation– Browse, search, update, print, etc

• uvhd – sample EBCDIC file display– uvhd dat1ebc/custmas1 r256s3a

• uvhd – sample ASCII file display– uvhd dat2asc/custmas1 r256s3

• uvhdcob – sample record display– uvhdcob dat2asc/custmas1 maps/custmas1

www.uvsoftware.ca

COBOL Cross-References

• xcobcall1 – list called programs in each program

• xcobcall2 – crossref programs calling any 1 program

• xcobcopy1 – list copybooks in each program

• xcobcopy2 – crossref programs using any 1 copybook

- please see xcobcopy2 (most useful cross-reference)

• cobfiles - COBOL files report – organization, access, open-mode, recsize, copybook,

www.uvsoftware.ca

JCL Cross-References

• xjkshfile1 – list datafiles in each JCL/script

• xjkshfile2 – crossref programs using any 1 datafile

• xjkshprog1 – list programs in each JCL/script

• xjkshprog2 – crossref JCL/scripts using any 1 program

• Jobflow reports – generated from JCL+COBOL

• Show file I/O from step to step in multi-step jobs– Sample jobflow report

www.uvsoftware.ca

Converting DYL280 to uv…

• Sample#1 – file init (write 1 blank/zero rec)Mainframe DYL280 code

Equivalent uvcp

Equivalent uvcopy

• Sample#2 – add records to an indexed fileMainframe DYL280 code

Equivalent uvcopy

www.uvsoftware.ca

Pre-Programmed uvcopy jobs

• table2 – table summaries by arguments– Table entries limited only by memory

– Table dumped at EOF in argument sequence

– Percentages on every line of 100% total line

• Sample input data file

• Sample table summary report

• Operating instructions & console displays

• uvcopy job equivalent

www.uvsoftware.ca

Replacements for Mainframe Utilities

• (Dyl280,Easytrieve,QuikJob,Ditto,etc)• uvqrpg – Report Generator

– up to 8 control break fields & total levels– up to 100 accumulators per level– built in sort

• Sample input file• Sample output report• Sample uvqrpg code
