RE: Garbage being written, not sure why?

Some more info:

The &SQM variable in the CL program has the garbage in it.

So the question appears to be why is the Command front end screwing up the data being passed to the
CLP?

Thanks!

Subject: 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!
