1 PAT

 PAT, the object module patch utility, allows you to patch object files.
 
 The general form of a PAT command line is:
 
	[outfile]=infile[/CS[:number]],correctfile[/CS[:number]]
 
 outfile	is the file specification for the output file.  If
		you do not specify an output file, none is generated.
 
 infile		is the file specification for the input file.  This file
		can contain one or more concatenated object modules.
 
 correctfile	is the file specification for the correction file.
		This file contains the updates being applied to a
		single module in the input file.
 
 /CS		specifies the Checksum switch, which 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	specifies an octal value that directs PAT to compare
		the checksum value it computes for a module with
		the octal value you specify as :number.
