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 */
