IF THEN Statements

GDL Enthusiast — Thu, 26 Sep 2024 11:43:32 GMT

Hi,

If I write and IF THEN statement, the editor sometimes returns an error if I add an ENDIF on the next line. Most of the time it seems to run without error if I don't even add the ENDIF statement when creating a list of logic.

The editor seems to like ENDIF after a series of parameters e.g:

IF list = 0 THEN

item = 1

method = 2

ENDIF

The Editor has no fault with no ENDIF after the following logic:

IF list = 0 THEN item = 0

IF list = 1 THEN item = 1

Is there a clue as to when an ENDIF is required?

Many thanks, Matt

When the IF, THEN, command is all on the same line, you do not need the ENDIF (I still put it there anyway).

When the command is on a separate line, you must use ENDIF.

if condition has only one statement and (as Barry mentioned) then is on the same line, you don't need endif

That is helpful. It was one of those unknowns that is very pleasing to have a definitive answer to.

Thank you both Barry and A_Smith for your responses!
