The GOSUB statement causes execution of a local subroutine, after which execution will continue with the next line of code.
Where label refer to an existing label within the current source code.
The compiler does not check for the existence of a RETURN statement and if no RETURN statement is encountered the program will continue until the final statement and not return to the original GOSUB.
An example of use is as:
GOSUB Initialize ;* open files etc..
GOSUB Main ;* perform main program
GOSUB Finish ;* close files etc..
Initialize: * open files
Main: * main execution loop
Finish: * clean up after execution
Go back to jBASE BASIC.
