Question
This is my function to calculate the gcd of two numbers a
and b
. When I use Prgm and EndPrgm, it worked fine. However, it kept popping up an error message say "Invalid in a function or current expression" when creating a function :(. Any idea?
gcd(a, b )
Func
If a>b Then
a->t
b->a
t->b
EndIf
While b#0
a->t
b->a
mod(t, b)->b
EndWhile
Return a
EndFunc
No correct solution
