Re: OVRMSGF and QCMDEXC procedure

Specify the parameter as a fixed length with CONST OPTIONS(*VARSIZE).

The compiler will auto-magically convert the varying length to fixed length.

Because QCMDEXC does not expect a varying length field as a parameter -- how do you tell it to skip the length in the 1st two bytes?

Not that it's a whole lot different:

QCMDEXC(CmdStr:%Len(%trim(CmdStr)));

why calculate??? i use varying length fields for creating

the command

string then on the call i just use:

QCMDEXC(CmdStr:%Len(CmdStr));

Thanks,

Re: OVRMSGF and QCMDEXC procedure






You're way ahead of me then (as usual :-) ). For most things the QCMDEXC procedure works just fine and it seemed cleaner to let the procedure calculate the command length, but you're right --

it's not

much and it avoids the occasional scoping problems.

the override was gone. I guess I should of realized this since a procedure is another entry on the call stack.
