From the Posix Shell
The Posix shell does not have the concept of a Parm value. Previous versions of Qedit still try to retrieve the value and are ending up with unpredictable values causing unpredictable behavior. To get around this problem, Qedit tries to determine where it is running from. If it is run from the standard Posix shell, sh.hpbin.sys, Qedit assumes the parm value is entered via the -P argument. For example, to run Qedit with a value of 67 from the Posix shell prompt, one would enter:
/ROBELLE/PUB/QEDIT -p 67
All arguments are retrieved as if they had been entered in the MPE Info= string. So, any feature supported by the Info= mechanism also works from the Posix shell.
