Hi All,

I gave this AND operator in REXX but it is not working in that way


it go inside loop only both condition is satisfied..
but it's not happening
!!

NUMBER OFF ?

Paste ALL code, and not just some cut-out stuff!

The logic is wrong, try with OR instad:

Unless you 'Pull' LAST before your Do While LAST will have the value 'LAST'.

Why did you not run a trace before posting - you would have seen this at that point.

And as an efficiency point - why calculate the length of LAST more than once?

NicC has a valid point, you should initialize variables before using DO WHILE. In this particular it doesn't matter as the DO WHILE is at the start of the program so all variables have their default values (their name in uppercase).
I would turn the thing around and do

then you don't need to worry about variable contents before the loop. And I find it cleaner too testing for EQ instead of NE.

IMO
in any well behaved REXX script ALL the variables should be initialised
and an ON VALUE clause be specified
