Using the QzshSystem Qshell API

Group,

This was also posted to the Java-l
list and is included here at the
list moderator's suggestion:

After creating an RPGIV procedure
that calls QzshSystem, I can't seem to
get it to work. I always get a return
code of 7 and a message that the
file was not found. My best guess is
that it is expecting the command to
be passed as ASCII. The API is pretty
simple and I thought I would have
this running in a few minutes, instead
I have spent a couple of hours
with no luck.

I have tried various prototypes for
the API, including

DQzshSystemAPI    PR            10I 0 EXTPROC('QzshSystem')
D PR_Cmd                          *   VALUE

and

DQzshSystemAPI    PR            10I 0 EXTPROC('QzshSystem')
D PR_Cmd                      5000A   CONST

and

DQzshSystemAPI    PR            10I 0 EXTPROC('QzshSystem')
D PR_Cmd                      5000A   VALUE OPTIONS(*STRING)

I think any of these should work.

Here is an example of what I have tried:

C                   EVAL      CmdStrLen = %LEN(%TRIM(Cmd)) + 1
C                   ALLOC     CmdStrLen     pCmdStr
C                   EVAL      %STR(pCmdStr: CmdStrLen) = Cmd
C                   EVAL      RtnCod = QzshSystemAPI(pCmdStr)
C                   IF        RtnCod <> *ZEROS
C                   CALLP     SndUnixErr('Error in Qsh Command: ' +
C                                          %TRIM(Cmd))
C                   EVAL      RtnErr = *ON
C                   ENDIF
C                   DEALLOC                 pCmdStr

Does anyone have any ideas?

Thanks,
