what do You mean by REVERSE :
1) 12345 ==> -12345
2) 12345 ==> 54321

the question as posed just deserves the picky comment ...
this is an forum for professionals, no a puzzle solving one!
why should we waste waste time on something of little use !

also the question You ask is not related to the topic being discussed here,
learn to post things properly ( in this case start a new topic )
it will save for the moderators the work of making things right
cheers

Hello and welcome to the forum,

When you have a question, you should start a new topic for your question rather than posting a reply to some unrelated topic. . .

What do you mean by "reverse"?
NOTE:(REVERSE OF NUM WITHOUT USING ANY TEMP AND COBOL COMMNDS)
If you cannot use "commands" you cannot write code. Code is a series of commands. . .
Hope this helps,

In COBOL, but without any COBOL commands?

Maybe Krishna or any other divine entity of your liking can do this...

01 Thenumber.
     05  Thefirstcharacter PIC X.
     05  FILLER                 PIC X.
     05  Thelastcharacter  PIC X.

Put your three-digit number to be reversed into Thenumber.

Then your preferred conditional construct which says:

If Thefirstcharacter equals "1", put Thelastcharacter into Thefirstcharacter and put "1" into Thelastcharacter, otherwise if Thefirstcharacter equals "2", put Thelastcharacter into Thefirstcharacter and put "2" into Thelastcharacter, otherwise, etc

In the real world, should also validate that the original "number" is actually a number.
   


Can't think why you'd want to do this, except for homework. I think all the "big guys" on here are very patient, although having to make the same points repeatedly. Don't just ask for your homework to be done for you, have a go at it and if you get struck, show what you've done and explain the problem you have. Show what should happen to the data, and what does happen with your code.

Yup, lots of what we do here is answer student homework questions.

This is one of the main reasons this forum was opened :)

Sorry about that, even though I now see it staring at me at the top of each screen, I didn't realise. Perhaps I was put off by other contributors to this thread (and other threads), with your graceful exception.

even considering the extenuating circumstance of the language barrier
too many people around here lack the basic skill of expressing clearly their needs...
or are they just lazy and careless ?

from my forum(s) experience, most often the second one applies!

I see your point well, so I've started some topics in the suggestions bit of the board.

I'm not trying to be personal about anyone, by the way, but I saw some comment about this board being for "professionals" or something. Kinda gave me the wrong end of the stick, that one.
