  Quote  When calling a subroutine you can supply less than the required number of values and in that case the missing values will be assumed to be either zero or an empty string.
BYVAL appears not to adhere to that.
> LIST
' Test prog 1
Dim integer a=5, b=6, c=7
 Print "a, b, c =";a;b;c
test a,,c

Sub test(BYVAL a, BYVAL b, BYVAL c)
If a = 5 Then
 a = 10
 Print "In Sub a, b, c =";a;b;c
EndIf
End Sub

Print "After Sub a, b, c =";a;b;c
> RUN
a, b, c = 5 6 7
In Sub a, b, c = 10 6 7
After Sub a, b, c = 5 6 7

Print "After Sub a, b, c =";a;b;c

In Sub a, b, c = 10 0 7
After Sub a, b, c = 5 6 7

BYVAL appears to be the default anyway.

Senility advancing.
