If I have an if statement that is long and I want to continue it to another line, what is the format? The typical & (carriage return) + format is being flagged as a syntax error.

This works

if 'abc' = 'bcd' or &
    'cde' = 'cde' then
    // Code here
end if

Assignment continuation:



ls_string = "blah blah blah" + &

"some more stuff"

Sorry Ronald, not trying to be "smart" but to avoid confusion, do you mean assignment "concatenation"?

Ronald = Roland? ;-)

The ampersand character initiates statement *continuation* across "immediately following" line break.

And it is true that in Roland's case the continuation happens in the middle of a string *concatenation*.

Agree with David, as soon as you introduce &-continuation in an IF-THEN you should prefer the long variant IF-THEN + END-IF. Look at END-IF as PowerScript's "curly braces" variant.

If you post your invalid syntax I'd be happy to look for why it fails.
