Kewl.  Thanks.  I think I'll be using this a lot more now that I've gotten 
my feet wet.  Amazing, been programming for 6 years but too afraid to try 
this because thought I'd screw it up.  But it would seem that it's pretty 
easy to learn and use.  I can see many ways to use this too for repetive 
functions that I currently use a subroutine for :).

RE: Prototype Calls






The short answer is NO.
VARYING with CONST means that the value you specify will be turned into a
temporary variable that is defined as a VARYING field. QCMDEXC does not
accept or know about that kind of data type, Therefore the call will fail
every time.
If you want to avoid using the length parameter, try the C runtime 
library's
'system' function. Here's the prototype for it.

     D system          PR            10I 0 ExtProc( 'system' )
     D  szCmd                          *   Value Options( *String )

You call it just like QCMDEXC (once QCMDEXC has been prototyped) except 
you
only have to pass the command string, as follows:

  C             callp   system('ADDLIBLE  cozzilib')

Let's look at the szCMD parm.

* means it is a pointer that is passed.
VALUE means the pointer value is passed by value instead of by reference.
OPTIONS(*STRING) means convert the value you specify into a C null
terminated string.

The combination * VALUE OPTIONS(*STRING) basically means you can specify 
any
character field or literal and the compiler converts that value into a C
null terminated string for you. A null terminated string is what the
'system' function requires.

Sorry,

    d Cmd             s           3000A 

Should I use Varying here?

Re: Prototype Calls







If cmd is defined as VARYING, there is no need to use %trimR(). I don't 
see
the definition of CMD.

Thanks,

Ahem,
Writing a new program where I'm using QCMDEXC and I prototyped the call :)
 First time I've used this, and I have to say.  Very KOOL.  No more coding
Exsr over and over lol.  Be gentle it's my first one.

     D*--------------------------------------------------
     D* Procedure name: Qcmdexc
     D* Purpose:        To allow the running of CL commands
     D* Returns:
     D* Parameter:      Cmd => Command to run
     D* Parameter:      CmdLen => Length of command to run
     D*--------------------------------------------------
     D Qcmdexc         PR                  EXTPGM('QCMDEXC')
     D  Cmd                        3000A   Options(*VARSIZE) Const
     D  CmdLen                       15P 5 Const

     ?* Remove library for CoolSpools just in case already there
     c                   Eval      Cmd = 'RMVLIBLE LIB(CVTSPLV4R1)'
     c                   CallP(E)  QCmdExc(Cmd:%Len(%TrimR(Cmd)))

This is the correct way yes?
