Parameters 

formaldesig           character array (required) 

                      Returns the fully qualified MPE syntax name of the
                      program being executed by the calling process.

                      The formaldesig parameter must be at least 28 bytes
                      in length in order to contain the longest possible
                      MPE syntax file name with delimiters.  The lockword
                      is not returned.  The first and last characters of
                      the returned value are blanks that act as
                      delimiters.

status                32-bit signed integer by reference (optional) 

                      HPMYPROGRAM returns a NM Loader error 128 when the
                      program name is not represented using the syntax
                      that the user specifies.

                      Returns the status of the HPMYPROGRAM 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 HPMYPROGRAM is 104.

length                32-bit signed integer by reference (optional) 

                      Returns the length (in bytes) of the file name
                      returned in the formaldesig parameter (including
                      the two blanks that act as delimiters).  A zero
                      returned indicates that no file name is returned.

myprogram             character array (optional) 

                      Returns the absolute pathname or fully qualified
                      MPE syntax name of the program being executed by
                      the calling process.

                      The myprogram parameter contains the name with
                      delimiters.  The first and last characters of the
                      returned value are blanks that act as delimiters.

myprogram_length      32-bit signed integer by reference (optional) 

                      On input, the myprogram_length parameter specifies
                      the maximum myprogram length in bytes.  On output,
                      myprogram_length returns the actual length of
                      myprogram, including the surrounding delimiters.

                      If myprogram_length is not correct upon input,
                      variables allocated near myprogram can be
                      overwritten, or an error could occur.  If the
                      myprogram_length parameter is not specified,
                      HPMYPROGRAM determines if the myprogram parameter
                      is long enough to hold HPMYPROGRAM to be returned.

                      Note that a value is not returned in
                      myprogram_length if you do not specify the
                      myprogram parameter.

myprogram_syntax      32-bit signed integer by reference (optional) 

                      On input, the myprogram_syntax parameter specifies
                      the syntax that is used when HPMYPROGRAM returns
                      the name in myprogram.  On output, the actual
                      syntax is returned in myprogram_syntax.  This is
                      only useful when MPE-escaped syntax is used.  The
                      name can be either a MPE syntax name or a HFS
                      syntax name.

                      The possible syntaxes are:

                      0                     MPE-escaped syntax

                      1                     MPE-only syntax

                      2                     HFS syntax

                      The default is MPE-only syntax.  Note that if the
                      myprogram parameter is not specified, no value is
                      returned in myprogram_syntax.

Operation Notes 

The HPMYPROGRAM intrinsic returns the fully qualified file name of the
program being executed by this process.  You can pass this name to the
HPGETPROCPLABEL intrinsic in the firstfile parameter.  HPGETPROCPLABEL
searches the files in the binding sequence for a procedure, beginning
with the program file.  The program file is the first file in the binding
sequence of the calling process.
