Function calls and passing parameters

A sub-function must be defined before its execution and is therefore placed before the main() macro function. If
there is an entry attempt into a function before it is first defined in the macro program will create a compiler error
'Function not defined'.
Sub int SQR(int x)
number
x = x * x
return x
Examples
For n = 100 Down 0 Step 3
n = n * 2
Next n
For loop = 0 To 20 Step 2
loop = (loop + 1) *2
Next loop
Examples
