I would like to break a spool file into pieces according to the media I'm going to save it to (CD, diskette, etc.). Is the any way to determine the size of the spool file within RPG program (infds)?
You can use the API QUSRSPLA. Located at offset 1472 or the return variable you will find the spooled file size. You will also need the size multiplier located at 1476 in order to get bytes, kilo, mega, ect.
It should look something like this:
/copy qsysinc/qrpglesrc,QUSRSPLA D RtnVar Like(QUSA010001) D RtnLen 10I 0 D APIFmt 8A Inz('SPLA0100') D JobFull 26A Inz('JOBNAME USER 000001') D IntId 16A D IntSplID 16A D SplfName 10A Inz('QSYSPRT') D SplfNbr 10I 0 Inz(-1) D SizeBytes 20I 0 * This is in the normal call format C Eval RtnLen = %Len(QUSA010001) C Call 'QUSRSPLA' C Parm RtnVar C Parm RtnLen C Parm APIFmt C Parm JobFull C Parm IntId C Parm IntSplID C Parm SplfName C Parm SplfNbr * C Movel RtnVar QUSA010001 C QUSSFILS Mult QUSSSM02 SizeBytes
