ENTER cataloged-program-name
ENTER @variable |
| Category | BASIC |
| Type | Statement |
| Description |
transfers control to another cataloged FlashBASIC program.
The program that is executed using the "enter" statement must be a cataloged verb in the current md, and may not be a subroutine. The program executing the "enter" statement need not be cataloged. All variables passed between programs must be declared by a "common" declaration in all program segments that are to be entered. All other variables are initialized upon entering the program. The common area grows or shrinks if the size is different between programs. Control does not return to the original program. In this way, "enter" is much like "chain" except that "enter" must be used to activate another FlashBASIC program and nothing else. The "at sign" (@) indicates that the program name is stored in the specified program variable. Without the "@", the "variable" name is taken literally. |

| Example |
program first.prog
common x,y,z x = 5 enter second.prog program second.prog common x,y,z print x stop In the above example, a "5" would be output. In the example below, the program name is stored in a variable. program first.prog common x,y,z x = 5 pgmname = "second.prog" enter @pgmname |
| Warnings | "enter" must not be used from a subroutine. |
