Well, I will be polite about it Regular expressions may indeed not be the ideal way to do pattern matching. I recall that there was another alternative named SNOBOL, but it did not really catch. The reality is that regular expressions became THE standard in text pattern matching, a standard that is used by virtually all popular languages on all popular platforms (whether those platforms are better or worse then the mainframe is not the issue here.) The glaring exceptions are the mainframe (z/OS) main languages COBOL and PL/1 and their platform which does not provide this capability. The Rexx 'parse' is much weaker and much less functional then regular expressions. So John, if your complaint is that regular expressions are not ideal, I may sympatize with you. But if you say that this capability is not important and should not be adapted because you do not find any use for it, in that case you actually illuminate my argument. In that case I will put my argument in another way, the mainframe platform is stagnant and there is no room for any refreshment according to those who see it this way. Stagnation is the first sign of death.

Honestly, I have used minimal regular expressions and found it to be obtuse, arcane obfuscation that is valued because it's the only text handling capability that Unix-land values. Ooh, YOU are smart enough to do it, and any SMART programmers should know how to use it. What a load of bull. It is awful to read and it does NOT need to be that way. The forward slashes and back slashes all over the place is crap and ought not to be forced down ANYONE'S throats. What a load of rubbish. I will NOT be polite about it. And your arrogance re the mainframe about it dieing. That's crap from pc-land, which is utterly a self-fulfilling prophecy, which sadly, due to management buy in to the lie, will eventually be done. Right now, mainframe is a living, viable, important resource for any large company. From the start, the advent of pc clusters has radically increased the cost infrastructure of all large companies. It sucks, and is only NOW starting to imitate what the mainframe did 60 years ago. Ooh, you are imitating the dinosaur. Nice. So, you prove the dinosaur was valuable after all, thus contradicting your own argument that is a useless thing. Bravo. Typical pc hypocrisy. -------------------------------------------- This message and any attachments are intended only for the use of the addressee and may contain information that is privileged and confidential.
