Remove the parenthesis from around args.

Code: (Select All)
declare sub main
declare sub get_numeric_args(args() as double)

DIM args(4) AS DOUBLE
get_numeric_args args()
PRINT args(1)


SUB get_numeric_args (args() AS DOUBLE)
    args(1) = 123
END SUB

It's a long standing glitch with arrays, and one that just happens to be a real PITA to track down and sort out. Wink

That fixed it!
Thanks!

I was almost fooled by what's going on. In QuickBASIC the programmer who wanted to use parenthesis so much for a subprogram (not "FUNCTION") call must use "CALL" statement like this:

Code: (Select All)
CALL get_numeric_args(args())

In QB64(PE) don't use parenthesis around a parameter list for subprogram call. This is not C, it's easier than that. :tu:
