plabel.

Functional Return 

plabel                16-bit unsigned integer (assigned functional 
                      return) 

                      Plabel of the target CM procedure.

Parameters 

procname              character array (required) 

                      Passes an ASCII procedure name, left-justified and
                      blank-padded.  The name can have a maximum of 16
                      characters.

library               16-bit unsigned integer by value (required) 

                      Passes indicator of the CM segmented library to be
                      searched.  The valid values are:

                         Value    Meaning 

                           0      Search the system SL only.  (Default)

                           1      Search the logon account SL, then the system SL.

                           2      Search the logon group SL, then logon account SL, and
                                  then system SL last.

                           3      Search the program file's account SL, then the system
                                  SL.

                           4      Search the program file's group SL, then the program
                                  file's account SL, and then the system SL last.

status                32-bit signed integer by reference (optional) 

                      Returns the status of the HPLOADCMPROCEDURE
                      intrinsic call.  If no errors or warnings are
                      encountered, status returns 32 bits of zero.  If
                      errors or warnings are encountered, status is
                      interpreted as two 16-bit fields.

                      Bits (0:16) comprise status.info.  A negative value
                      indicates an error condition, and a positive value
                      indicates a warning condition.  Refer to the MPE/iX 
                      Error Message Manual Volumes 1, 2 and 3 
                      (32650-90066, 32650-90152, and 32650-90368) for a
                      description of its value.

                      Bits (16:16) comprise status.subsys.  The value
                      represented by these bits defines the subsystem
                      that set the status information.  The subsystem
                      identifier for HPLOADCMPROCEDURE is 105.

Operation Notes 

The HPLOADCMPROCEDURE intrinsic helps you avoid switching by name
overhead.  Switching by name incurs the overhead of forming a hash probe
out of the target procedure's name and finding the name in a hash table
in order to obtain the procedure's plabel.  You can eliminate this
overhead by obtaining the target procedure's plabel through the
HPLOADCMPROCEDURE intrinsic.  You can then supply the result returned by
HPLOADCMPROCEDURE as the value of the procname parameter in the call to
the HPSWITCHTOCM intrinsic.
