Passing Information to a Process 

When your program creates a process, it can programmatically pass
information to the child process with:

 *  The param parameter of the CREATE intrinsic

 *  Item numbers 2 and/or 11 of the CREATEPROCESS intrinsic

 *  The parm and/or info parameters of the :RUN command

The GETINFO intrinsic enables your program to retrieve this information.

This is an example of a GETINFO intrinsic call:

     GETINFO (INFO,MAXLENGTH,PARAMETER);

The parameters specified in the example are described below.

INFO             Returns the contents of the info parameter from the :RUN
                 command or Item Number 11 from CREATEPROCESS.

MAXLENGTH        Passes the maximum number of characters that MPE XL is
                 allowed to move to INFO. MAXLENGTH returns the number of
                 characters actually moved to INFO by MPE XL. MPE XL will
                 not move a number of characters greater than the
                 original value of MAXLENGTH.

PARAMETER        Returns the contents of the parm parameter from the :RUN
                 command, item number 2 from CREATEPROCESS, or the param 
                 parameter from CREATE.
