RE: Does Qcmdexc return an error ??

Rory and Crispan,

Note that I said "supposed to be" I did not say it "must be".
Similar to saying %trimr(cmdstrg) Is not necessary.

Saying that the parm must be the length of the field passed, is not correct,
hence wrong.

-Bob

The command length, passed to the QCMDEXC program on the second parameter,
is the maximum length of the passed command string. Should the command
string be passed as a quoted string, the command length is exactly the
length of the quoted string. Should the command string be passed in a
variable, the command length is the length of the CL variable. It is not
necessary to reduce the command length to the actual length of the command
string in the variable, although it is permissible to do so.

Right, but wrong.
The second parm is supposed to be the length of the command string passed
in
parameter 1, not the length of the variable passed in parameter 1.

Barbara,

Correct me if I'm wrong, but surely you can use:

C Eval MyCmd = 'DSPFD FILE(XYXYXYZ) ' +
C 'OUTPUT(*PRINT)'
C CallP(E) QCMDEXC(MyCmd:%Len(MyCmd))

whether or not you specify Varying. The second parameter to QCMDEXC
defines
the length of the first *parameter*, not the length of the *data* in that
parameter - QCMDEXC will ignore any trailing spaces in the first
parameter.

I remarked on this a while back, when pointing out that people were adding
totally unnecessary %trim's in their code...

And if you define MyCmd as VARYING, you can simplify further by
eliminating the %trim:
C Eval MyCmd = 'DSPFD FILE(XYXYXYZ) ' +
C 'OUTPUT(*PRINT)'
C CallP(E) QCMDEXC(MyCmd:%Len(MyCmd))
