Re: TED's Explanation of Y2K Programming Tools

I'll try to put things in layman's terms...

Most always, applications consist of smaller program modules that need to be "stitched" together when the software is compiled (i.e. turned from stuff we can read into machine specific code). Just as one can extract water from soup to enable it to fit in a smaller can, one can apply a number of compression algorithms to computer code so that it takes up less disk space. [PK-ZIP is an example of a popular PC-based compression program.]

Compression is all well and good if you have a way to expand what you've shrunk. If I read TED correctly, he is saying that using a PC based tool like those from PTUS and ZITL are worthless when trying to find code on a mainframe because only the program that compressed it in the first place can decompress/understand it-- and this program does NOT run on a PC.

The conclusion is, unless you have a mainframe based tool, like ALYD's SmartCode, lots of luck trying to remediate mainframe based applications.

P.S. Woops, just saw TED's last post... so never mind!
