Fnend

The FnEnd (FN) and End Def statements indicates the end of a definition of a multi-lined User Defined Functions.

Comments and Examples

If a user-defined function uses more than one statement, it must be terminated by an FnEnd statement.

Syntax

Technical Considerations

1.) A user-defined function definition may appear anywhere in the program, either before or after the function is invoked. Unlike subroutines, functions are bypassed when encountered in normal program flow.

2.) The FnEnd statement is considered descriptive and does not affect the value of the function.

3.) If a function should return a value, it must be assigned using a LET statement before FnEnd is encountered. The LET must appear in the following format:LET FNname=expression

4.) FnEnd must be the last statement on a line.
