Using Qshell QzshSystem API

["David Morris" <David.Morris@xxxxxxxxxxxxx>]

Group,

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,
