hi Shriya,

Evaluate condition is used when you need to check the same variable with different values and evaluate true is used for checking different variables.

for eg: A can have values 1 or 2 or 3.

Evaluate A
when '1'
*******
when '2'
******
when '3'
*****

Even u can use evaluate true here like

Evaluate true
when a = '1'
****
when a = '2'
****

but generally used in cases like
evaluate true
when a='1'
********
when b='2'
**********

hope this is clear.

Thanks,
Anu

hi Shriya,

What anuradha says is true, but it doesn't go far enough.

Eval tests the "value" of a variable.
Eval TRUE tests the TRUTH of a "conditional" stmt.

These stmts can take various forms and levels of complexity, E.g.:

WHEN (FLD-A IS NUMERIC AND FLD-B >= FLC-C) OR FLD-Z = '10'

HTH, Jack.
