SBasic language reference::Sub statement

Sub statement
Declares the name, arguments, and code that define a Sub procedure.

Format:

  Sub name [(arglist)] 
     [ statements ]
     [ Exit Sub ]
     [ statements ]
  End Sub

Syntax:

name
Required. Name of the Sub procedure. Must be a valid identifier.
arglist
Optional. List of variables or expressions representing arguments that are passed to the Sub procedure when it is called. Multiple arguments are separated by commas. If you supply an argument list, you must enclose it in parentheses.
statements
Optional. A block of statements to be executed within the Sub procedure.
End Sub
Terminates the definition of this Sub procedure.

Remarks:

1. You can't define a Sub procedure inside another procedure.

2. The Exit Sub statement causes an immediate exit from a Sub procedure. Any number of Exit Sub statements can appear anywhere in the procedure.

4. It's possible to call other functions and subs in function procedure but they have to be declared before current sub.

5. SBasic supports recursion calls, it means you can call current Sub inside it's body.

Example:


  Sub WriteSomeLine(s as String)
     Print
     Print s
     Print
  End Function 

  ' -----------------------------------
  WriteSomeLine("some text")
