Substring of a variable

[kaeserea]

Hello!

Does anybody know how to get a substring out of a variable and store this substring in another variable?

I tried
[tt]
-SET &WF = 'blubb';
-SET &ST = SUBSTR(5, &WF, 2, 2, 1, &ST);
[/tt]

But this does not work. I guess this is due to the fact that SUBSTR is used with COMPUTE and DEFINE normally.

Hello Eva,

Try this:
-SET &WF = 'blubb';
-SET &ST = '?';
-SET &ST = SUBSTR(5, &WF, 2, 2, 1, &ST);

Hope this Helps

The doc states that the last arg, when used in Dialogue Manager MUST be the FORMAT of the returned value. Code it like this:

-SET &WF = 'blubb';
-SET &ST = SUBSTR(5, &WF, 2, 2, 1, 'A1');

and it works like a charm.
