Re: Garbage being written, not sure why?

I'm trying to track down an problem we've having on a TEST box, the production box is running the same
programs with apparently no issues.


It seems that on the test box, the program is writing garbage. Here's the scoop:


Command:

CMD PROMPT('Build FTF Options File')

PARM KWD(SQM) TYPE(*CHAR) LEN(48) MIN(1) +

PROMPT('Source queue manager')

PARM KWD(SPATH) TYPE(*CHAR) LEN(64) MIN(1) +

PROMPT('Source file')

PARM KWD(DQM) TYPE(*CHAR) LEN(48) MIN(1) +

PROMPT('Destination queue manager')

PARM KWD(DPATH) TYPE(*CHAR) LEN(64) MIN(1) +

PROMPT('Destination file')


Command processing program:

PGM PARM(&SQM &SFILE &DQM &DFILE)

DCL VAR(&RTNCD) TYPE(*CHAR) LEN(7)

DCL VAR(&SQM) TYPE(*CHAR) LEN(48)

DCL VAR(&DQM) TYPE(*CHAR) LEN(48)

DCL VAR(&SFILE) TYPE(*CHAR) LEN(64)

DCL VAR(&DFILE) TYPE(*CHAR) LEN(64)


CALL PGM(PRC008R) PARM(&RTNCD &SQM &SFILE &DQM &DFILE)


RPG IV Program:

FFTFOPTION O A F 1024 DISK

D*

D SrcLin DS

D SrcRsv 1 12S 0

D SrcDta 13 1024A

D*

D cRtnCd S 7A

D cSqm S 48A

D cSfile S 64A

D cDqm S 48A

D cDFile S 64A


C *Entry PList

C Parm cRtnCd

C Parm cSqm

C Parm cSfile

C Parm cDqm

C parm cDFile

C Eval cRtnCd = *Blank

C Eval SrcRsv = 0

C Eval SrcDta = '-sqm ' + cSqm

C Write FTFOption SrcLin 99

C Eval SrcDta = '-dqm ' + cDqm

C Write FTFOption SrcLin 99

C Eval SrcDta = '-spath ' + cSfile

C Write FTFOption SrcLin 99

C Eval SrcDta = '-dpath ' + cDfile

C Write FTFOption SrcLin 99



There's actually a number of other parameters, but the SQM and QDM ones, which end up as the first two
lines of the source file are the ones getting garbage.


The only thing I see, is that the FTFOPTION file, which is actually a source file with a record length
of 268 is defined in the RPG program as an internally defined file with a record length of 1024. Not
sure why this was done this way; but it does throw a "CPF4011 - Buffer length longer than record for
member FTFOPTION." (Severity 10) which I would expect.


A clue as to what is going on, is that the garbage that ends up in the source file, is from the
corresponding xPATH variables. So for instance, with this invocation:

PRC008C SQM(TEST) SPATH('\dummy\fld\infld\what') DQM(C092DV21) DPATH('\dummy\out\outfld\so')


I end up with this in the SRCDTA field of the source file:

-sqm TEST \dummy\fld\infld\what
-dqm C092DV21 \dummy\out\outfld\so

Looking at the RPGIV program in debug, cSQM has the value of "TEST
\dummy\fld\infld\what".


But I don't understand why.


What am I missing here?


Thanks!
