[open-cobol-list] RE: Question About Functions

[Robert Sherry]

Roger,
     I think I am starting to get this. What about this case:
            FUNCTION MAX( A   (B - C)        -D )
Here I am thinking that -D is going to come back from the scanner as two
tokens. I am thinking the - in -D should be treated as a binary minus and
therefore we have 2 arguments to MAX. Do you agree with my reasoning?

Indisputedly two.
What about this :
FUNCTION MAX( A   (B - C)        - 3 )

You think 3? Wrong, still 2.

BUT :
FUNCTION MAX( A   B - C        -3 )
Note no space between the "-" and the "3".
That's 3 parameters. The beauties of the unary minus.
