Hi all,

Is there any body who is using JSP Technique in programming. If so, can you please share material or any thing for my understanding. If not at least, is it possible to illustrate with the help of an example in cobol. Thanks a lot for your efforts.

Cheers,
-Mike.

I Googled (which you could have done also) "Jackson Structured Programming" and got many hits.

This methodology was born in the mid 1970's and is just another flavour of structured programming.

If this is an Interview question, I would question why JSP is relevant today?

Since the introduction of COBOL II (mid 1980's), which took on many facets of PL/I, and as time marches on, structured programming (in general) is more of a conversation shared over a beverage rather than a mandated directive or a radical idea, for that matter.

Wikipedia on this.

There's an example in the article.

I've never heard of it until now. But it's actually quite interesting. The idea is to process batch files with explicitly coded Finite State Machines. FSMs are also regular languages (expressions) and have corresponding state transition diagrams. But then the input has to be expressable as a regular language which should generally be the case anyway..
