Answer Posted / manish kumar
MAPFLD is used to change the format of the fields used in
the OPNQRYF statement. When I say changing the format the
format of the field will not be changed but we can format
the data as we wish and store it in a diffrent variable.
For eg. You want check for year to be some value and are not
concerned abt date and month then you can follow as below.
OVRDBF FILE(FILEA) SHARE(*YES)
OPNQRYF FILE(FILEA) QRYSLT('YEAR *EQ "88" ') +
MAPFLD(YEAR '%SST(DATE 5 2)' *CHAR 2)
CALL PGM(PGMC)
CLOF OPNID(FILEA)
DLTOVR FILE(FILEA
