Syntax
SUB Name[(var1)]

Remarks

name Name of the sub procedure, can be any non reserved word.
var1 The name of the parameter.
You must end each subroutine with the END SUB statement.

You must Declare Sub procedures before the SUB statement.
The parameter names and types must be the same in both the declaration and the Sub procedure.

Parameters are global to the application.
That is the used parameters must be dimensioned with the DIM statement.
Therefore, the variables can be used by the program and sub procedures.
The following examples will illustrate this :

Dim a as byte, b1 as byte, c as byte 'dim used variables
Declare Sub Test(a as byte) 'declare subroutine
a = 1 : b1 = 2: c = 3 'assign variables

Print a ; b1 ; c 'print them

Call Test(b1) 'call subroutine
Print a ;b1 ; c 'print variables again
End

Sub Test(a as byte) 'begin procedure/subroutine
print a ; b1 ; c 'print variables
End Sub
