Main Program Procedure The main program of a compiled program is not an outer block, but a procedure. The outer block of a compiled HP Business BASIC/XL program initializes the program and then calls the main program. The name of the outer block is always BB_PROGRAM. The name of the main program procedure is the upshifted name of the file that contains the program source code; for example, if the filename of the file containing the program is MYPROG.MYGROUP, the main program procedure name is MYPROG. The main program procedure can be put into an executable library and called as an external subunit. If you compile a program from within the interpreter without specifying the name of the file, the name of the current program will be the name of the main procedure entry point. If the current program does not have a name, BBCINP will be the entry point name. See "Calling External Subunits from Interpreter" later in this chapter for more details.
