Perform one extra pre-step in your process, or

Replace one type of statement with another, or

Add one line into or before your request, or

Issue just one additional SET statement, or

Increase the appropriate default limit value

"If you live to the age of a hundred you have it made because very few people die past the age of a hundred.”

George Burns

Use JOIN instead of WHERE IN FILE

TABLE FILE CARPRINT COUNTRYWHERE COUNTRY NE 'ENGLAND'ON TABLE HOLD AS VALUES FORMAT ALPHAEND

Use POOLED TABLES for multiple TABLEs

“Always get married in the morning. That way if it doesn’t work out, you haven’t wasted the whole day.”

Mickey Rooney

AVINGS: 1/nth of I/O’s where n is number of TABLES.S

Why extract the

entire database

four times?

SET POOL= ONSET POOL= ON

SET POOL= OFFSET POOL= OFF

•No HOLD file needed

•Extracts from database once

•Feeds all TABLEs at one time

•Output identical to no pooling

•Set ESTLINES/ESTRECORDS for even more efficiency

*Only for flat files via SEGTYPE

AVINGS: Average 50% search time; could save 1% or 99%.S

“The flat file is sorted on the screened field; stop searching when you see a larger value.”



“Somebody actually complimented me on my driving today. They left a little note on the windshield.

It said 'Parking Fine’.”

Tommy Cooper

Reformat fields inside the TABLE instead of DEFINE

DCOST/I6 AS ‘INTCOST’BY CAREND

No DEFINE needed(but creates extra field in matrix)

Hint: Extra field appears in a HOLD file. To remove, SET HOLDLIST=PRINTONLY

AVINGS: Only final displayed field is reformatted.S

“Getting on a plane, I told the ticket agent to send one of my bags to New York and the other to LA. She said

she can’t do that. I told her she did it last week”.

#Note:External Index is static - not updated per transaction. Must Rebuild Index if file changes, say nightly.

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

“I asked a fellow at hang-glider school 'How many successful jumps do you need before you graduate?'

He said, 'All of them.’ ”

Red Skelton

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 ... 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

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.


FILE=CAR,…SEGMENT=…,SEGTYPE=S1,$FIELD=VALUE1,,A5,$FIELD=VALUE2,,A9,FIELDTYPE=I,$FIELD=VALUE3,,A2,FIELDTYPE=I,$FIELD=VALUE4,,A1,FIELDTYPE=I,$FIELD=VALUE5,,A6,$. . .

Force use of the higher-hit index

“It’s money. I remember it from when I was single.”

Billy Crystal

AVINGS: Significant reduction in data access time.S


TABLE FILE CARPRINT ... WHERE VALUE3 LT '736‘ WHERE VALUE4 EQ ‘ABC‘ WHERE VALUE2 EQ 'Y‘ END

TABLE FILE CARPRINT ... WHERE VALUE3 LT '736‘ WHERE VALUE4 EQ ‘ABC‘ WHERE VALUE2 EQ 'Y‘ END

FOCUS automatically uses the first index,

regardless of how the screens are arranged

in the TABLE

Force FOCUS to use the most valuable Index. Only you know which

one that is!

Build test limit right into the Master “Curious people are interesting people.

AVINGS: No code to add, switch or comment out to do a test run.S


SET USER=TESTTABLE FILE CARPRINT ... WHERE FIELD1 LT '736‘END

Duplicate the same field in the MFD for multiple purposes(Interface-only technique)

“The prime minister held a meeting with the cabinet today. He also spoke to the bookcase and argued

with the chest of drawers.”

Ronnie Barker

AVINGS: Saves a DEFINE for sure, and maybe other coding.S


Duplicate ALIAS, different formats


CAR Master

TABLE . . .WHERE Order_Date FROM ‘01012000’BY Order_Month. . .

Want to screen on date, but sort/sum by month


DEFINE FILE ... LASTNAME2/A1 = EDIT(LASTNAME,’$9’);END

TABLE FILE ...PRINT ... IF LASTNAME2 EQ ‘M' IF EXCHANGE EQ '736' IF FLAG EQ 'Y‘END

DEFINE FILE ... LASTNAME2/A1 = EDIT(LASTNAME,’$9’);END

TABLE FILE ...PRINT ... IF LASTNAME2 EQ ‘M' IF EXCHANGE EQ '736' IF FLAG EQ 'Y‘END

Do string manipulation inside the TABLE when possible

“I only know two pieces. One is 'Clair de Lune' and the other one isn't.”

AVINGS: In-TABLE string masking is faster than DEFINE.S

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

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

$ means any one character$* means all remaining chars

Victor Borge



Store up to 99 parsed masters in memory, so no reparsing

“It’s no longer a question of staying healthy. It’s a question of finding a sickness you like.”

Jackie Mason

Avoid reparsing Masters over and over again

SET SAVEDMASTERS = 99TABLE FILE CARPRINT …ENDTABLE FILE CAR …TABLE FILE EMPLOYEE …TABLE FILE CAR …TABLE FILE SALES …TABLE FILE EMPLOYEE …

SET SAVEDMASTERS = 99TABLE FILE CARPRINT …ENDTABLE FILE CAR …TABLE FILE EMPLOYEE …TABLE FILE CAR …TABLE FILE SALES …TABLE FILE EMPLOYEE …

Never reparses on consecutive use

Without the SET, would: -- dump CAR master,-- parse EMPLOYEE, -- reparse CAR again-- parse SALES ….

SAVINGS: Large savings when constantly flipping Masters.
