Re: How can I Work with strings?

You can use the 'decode' function.

In your example, let's assume that the variable 'and_or' holds either 'AND' or  'OR'. You could write

... answer = decode(and_or,'AND','Y','OR','O',<default>) ..

Decode functions as a sort of immediate if. If you pseudo-coded the above  algortithm, it would look like this:

IF and_or equals 'AND' THEN

   answer = 'Y'
ELSE IF and_or equals 'OR' THEN

   answer = 'O'
ELSE
   answer = <default>
