Remembering past occurrence

[gateleys]

Hi,
I have a situation where I need to keep track of some past occurrence of a field value. Example: If InLink.Column = 'remember me' then I set a stage variable svIsRemember = 1. Now, as I process through other records, I check for occurrence of anohter string InLink.Column = 'String to change', that is EREPLACED with 'new String' if svIsRemember = 1. Note: svIsRemember is reset (=0) if I encounter a column with string 'Stop Remember'.

I could do it if I could write an IF statement without the ELSE clause. Can anyone suggest how I could do this?
Thanks,

gateleys

Hi,

I'm not sure if I got your point, but on a stagevar derivation you can specify something like

If in.field1='xxx' then 1 else stagevar

to keep the contents of stagevar "untouched" in the else case.

Best regards

In an expression you can not use statements. The conditional expression (IF test THEN value ELSE value) is an expression; it must always return a value and must, therefore, always have both a THEN part and an ELSE part.

The IF statement is only available in Routines.
