Charles,

>From the 'Language Environment Programming Guide',
 
PLIST indicates in what form the invoked routine should expect the argument 
list. You can specify PLIST with the following values under Language 
Environment: 

HOST The argument list is assumed to be a character string. The string is 
located differently under various systems as follows: 

     Under TSO, if a CPPL is detected, Language Environment gets the
     string from the command buffer. 

     Under TSO, if a CPPL is not detected, Language Environment assumes a    
     halfword-prefixed string in the MVS format. 

     Under MVS, Language Environment uses the halfword-prefixed string.

OS The inbound parameter list is assumed to be in an MVS linkage format in 
which register 1 points to a parameter address list. No run-time options are 
available. Register 1 is not interrogated by Language Environment.

The PLIST(HOST) setting allows the object to execute under MVS  
(assuming a halfword-prefixed string), or under TSO (using the CPPL or the
MVS-format parameter list). Specify PLIST(HOST) to default to the 
argument list format for the operating system under which your application
is running.

Another example using LINK and specifying a half-word prefixed length:

LINK EP=pgmname,PARAM=PPARM   
PPARM    DC    H'17',C'PARM1 PARM2 PARM3'

With ARGPARSE and PLIST(HOST) the results should be:

4                /* argc   */
pgmname     /* argv0 */
PARM1        /* argv1 */
PARM2        /* argv2 */
PARM3        /* argv3 */

Dave Waldman
