Coding of Logical OR in TSO REXX

[JohnCorbin]

Hi gang...

If I have code like

SELECT
WHEN code ='A' | CODE = 'B' | CODE = 'C' THEN
more code here
OTHERWISE
more code here
END
does the line code ='A' | CODE = 'B' | CODE = 'C'

read the same as code ='A' or CODE = 'B' or CODE = 'C'

Is there another way to code this ... I was thinking of


SELECT
WHEN code = 'A' THEN
WHEN code = 'B' THEN
WHEN code = 'C' THEN
more code here
OTHERWISE
more code here
END

Yes, the | is an or.

Just bear in mind that if you code;

WHEN code = 'A' | code = 'B' | code = 'C'

then your program is always doing 3 variable comparisons.

I prefer to minimise my comparisons by coding things like;

if index('A B C', code) > 0 then ...
