Hi,
First you need to create a TXT source in which you need to
provie the update command.
Next in CL program you should use the command RUNSQLSTM on
this source(TXT).
So whenever you have to change another record you need to
simply change and save the TXT source.
Examply:
Data on file, PF1:
FLD1 FLD2 FLD3
000001 001 AAA BBB
000002 002 BBB CCC
000003 003 CCC DDD
000004 004 XXX ZZZ
Member1, Name: PGM1 , Type: TXT
UPDATE PF1 SET FLD3 = 'CHG' WHERE FLD1 = '004';
Member2, Name: PGM2 , Type: TXT
PGM
RUNSQLSTM SRCFILE(LIB1/SRCFILE) SRCMBR(PGM1) +
COMMIT(*NONE)
ENDPGM
Compile the PGM2 and call it.
Now Result for data on PF1
FLD1 FLD2 FLD3
000001 001 AAA BBB
000002 002 BBB CCC
000003 003 CCC DDD
000004 004 XXX CHG
