Re: Counting occurrences of a string in loadlib

Hi

I would also suggest to load and compare.
We tried to search for some module id. string in a loded module, but we failed in the new program object format, as the LOAD not brings the
the complete text into the storage.

I have two load libraries (PDS's) that have different blocksizes. The
modules in the load libraries should be "logically" equivalent, but since the
blocksizes are different, they are not "physically" equivalent. I need to count
the occurrences of a given string (i.e., "change identifier") in each load module and come up with a total for each load library. I know I can browse each member and do a "FIND ALL...", but I would rather do the count in one shot for each load library.
ISPF 3.14 and 3.15 ("Search For" and "Extended Search For") tell me how many lines in each member contain the string and total number of lines containing the string in the load library. The problem with this is that in load library "A" (which has a block size of 32K), the string may occur three times on a single line in module PROGRAM1, but in load library "B" (which has a blocksize of 6144), the same logical data in PROGRAM1 takes up multiple physical records, so the string shows up on several lines instead of one, so the count of lines with the string don't match.


There's a bigger problem in any standard text search. I would expect there to be a reasonable chance of at least one of the strings being split across blocks (depending on string length, blocksize, and number of members). In that case, the string would not be found.

An annoying thing that I've run across is that even if the blocksizes are equal, an IEBCOPYed lmod might not be byte-for-byte equal with its source. (WAD - or WABD, where the B stands for "badly".)

Has anyone written a program to LOAD two modules and compare them? Or, are there gotchas in that technique, too?
