		     OBJECT MODULE PATCH UTILITY (PAT)
 
     The PAT utility, allows you to patch, or update, code in a relocatable
binary object module.  Input to PAT is two files, the original input file and
a correction file containing the corrections and additions to the input
file.  The input files consists of one or more concatenated object modules.
The correction file consists of object code that, when linked by the Task
Builder, either overlays or is added to the original object module.  Correction
input is prepared in source form and asembled by the MACRO-11 assembler.
 
     Both the Input file and the Correction file must be in object module
format.  The command string is as follows:
 
     [outfile]=infile[/CS[:number]],correctfile[/CS[:number]]
 
     correctfile - Contains the updates being applied to a single module
		   in the input file.
 
     CS - Checksum switch, directs PAT to generate an octal value for the
	  sum of all the binary data comprising the module in the file to
	  which the switch is applied.
 
     number - Octal value that directs PAT to compare the checksum value it
	      computes for a module with the octal value you specify as
	      number.
