DECLARE FUNCTION curiosity

[Flyzone]

If I declare a function (before use of the function) as:

Code: Select all

DECLARE FUNCTION GenSortKey (SortRec AS STRING,_
    SortKeyStartLoc() AS INTEGER,_ 
    SortKeyLeng() AS INTEGER,_ 
    SortKeySeq() AS STRING)_
        AS STRING

... I have no compile or execution problems.

However, if I declare the function moving the first parameter to a continuation line it then does not compile, such as:

Code: Select all

DECLARE FUNCTION GenSortKey_
    (SortRec AS STRING,_
    SortKeyStartLoc() AS INTEGER,_ 
    SortKeyLeng() AS INTEGER,_ 
    SortKeySeq() AS STRING)_
        AS STRING

This gives me the error ...
"Variable not declared, SortRec"

As a parameter, SortRec is not DIMensioned in either case.

Should that happen?

Use GenSortKey _ instead of GenSortKey_. Otherwise, the _ will be part of the function name, not a line continuation.

That does it. Thanks.

That does it. Thanks.

Kinda weird that the underscore is the ONLY special character that can be used in var names but is also used for continuation.
