SOMPATCH
Operation
• When running the program interactively, the current MODIFY command is not applied,
but all previous good MODIFY commands are applied.
• If the input to the SOMPATCH utility is coming from a patch file, and the SOM being
patched has not been built with a ypatch file, then the current MODIFY command is not
applied, but all previous good MODIFY commands are applied.
• If the input to the SOMPATCH utility is coming from a patch file, and the SOM being
patched has been built with a ypatch file, then none of the current patch (as specified by
the last LOG command) is applied.
Example

OFFSET
This command searches for a set of numbers in a range around a specified symbol.
Syntax
OFFSET
symbolname number0 [ number1 number 2 ... numbern ]
Parameters
symbolname Symbolname is an entry from the library symbol table or current SOM
dictionary.
numbern Number0 .. numbern is a sequence of numbers that the user is looking for.
The maximum is 10 numbers.
This command is used mainly in relocating a patch. When an NL is relinked, all those
patches that were not bound to their own entry-level procedure (refer to the SYMBOL
command) move around. The OFFSET command can be used to find their new location.
