Add one line into or before your request, or

Issue just one additional SET statement.

“My grandmother started walking five miles a day when she was sixty. She’s ninety-seven now,

George Burns

Most of the time, you don’t need the Internal Matrix

SET SAVEMATRIX = OFFTABLE FILE CARSUM DCOST

No need to create or preserve

the Internal Matrix?

When is SAVEMATRIX=ON needed ? See next slide.

Savematrix defaults to OFF in Rel 7.2+, but might be set ON in a site-wide profile.

AVINGS: Significant cost of creating a matrix that is not used.S

“I was going to have cosmetic surgery until I noticed that the doctor's office was full of portraits by Picasso.”

Rita Rudner

For constants, use an &Variable instead of DEFINE

-SET &INCR = 50 ;TABLE FILE CARSUM DCOSTCOMPUTE NEWCOST=DCOST + &INCR ;BY COUNTRY BY CAREND

“The IQ and the life expectancy of the average American recently passed each other,

Careful! You cannot always substitute DEFINE with COMPUTE.

JUMP


DEFINE FILE ... EXCHANGE/A3 = EDIT(PHONE,'$$$999$$$$'); FLAG/A1 = IF (SALARY + BENEFITS GT 50000) AND (EXCHANGE EQ '736‘) THEN 'Y' ELSE 'N';END

Test higher-hit fields first

AVINGS: Potentially significant reduction in calculation time.S

TABLE FILE ...PRINT ... IF LASTNAME EQ ‘$M$*' IF EXCHANGE EQ '736' WHERE FLAG EQ 'Y‘END

TABLE FILE ...PRINT ... WHERE FLAG EQ 'Y‘ IF EXCHANGE EQ '736‘ IF LASTNAME EQ ‘$M$*'END

Calculated first for every record -- and often false

Complicated calc done only when all other criteria pass

Do real fields first, or those most likely to eliminate records

Technique applies to fields on the same level. Higher level screens are always done first,

regardless of the order coded.

“The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!' but

'That's funny...‘ ”

Isaac Asimov

Do string manipulation inside the TABLE when possible

“????.”

Replace compound-IF in DEFINE with “WHERE”

Jackie Vernon

“When I was born my father spent three weeks trying to find a loophole in my birth certificate.”

DEFINE FILE ... TESTFIELD/A1 =

END TABLE FILE ...IF TESTFIELD EQ ‘Y'END

TABLE FILE ...WHERE (F1 EQ ‘ABC’) OR (F2 GE 27) END

compound situation
