1 IMGDEFINE
 The function of this command procedure is to build an Image Histogram
 definition file from a sample definition file and a program map file.
 The resulting definition file is then used to build a Bucket file which
 may then be used to generate Image Histogram reports (See HELP @IPSS
 IMGREPORT). 

 Syntax:
          @SYS$COM:IMGDEFINE map_file sample_def new_def bucket

 Also see HELP @IPSS IMGREPORT

2 Parameters
 map_file - is the name of the program map file.

    The map file is generated by the linker with the /MAP=filename
    qualifier.  The /FULL and /NOSYSSHR qualifiers are recomended to
    cause the program and therefore the map to include copies of the
    Run-Time library files.  NOTE:  /NOSYSSHR should ONLY be used for 
    Image Histogram generation.  If used for a production program it
    will cause the program to be larger, require more memory to run,
    and run slower because it can not share common code with other
    users on the system. 

 sample_def - is the name of the image histogram definition file
    (default is the map file name with a type of .DEF). 

    The sample definition definition file will have the following
    lines replaced by dynamically generated lines built from
    information in the map file. 

        DEFINE ADDRESSES: MAP "map_file.map" PSECT psect_name 

    If you specify SYS$COM:IMGDEFINE.DEF as the input image histogram
    definition file, you will get a basic definition which should get
    you started. 

 new_def - is the name of the new image histogram definition file
    (default is next higher version of the input definition file). 

 bucket - is the name of Bucket file (default is map file name with
    type of .BKT).  The bucket file is input to IMGREPORT (see HELP
    @IPSS IMGREPORT)

2 IMGDEFINE.DEF 
 There is a pre-build sample definition file stored in SYS$COM: called

    SYS$COM:IMGDEFINE.DEF

 This sample definition file if specified for 'sample_def' will 
 generate a histogram definition file that will account for all 
 PSECT's found in the program map supplied and for time spent in P1 
 space and system space.
