MENU and CHOICE instructions

MENU "menu description string"

CHOICE "choice identifier string"

instruction block for this choice

other CHOICE instructions

END MENU

MENU and CHOICE help you control a menu- and dialog-driven procedure. They present to the user a dialog box with mutually exclusive choices. MENU and CHOICE are useful when you need the user to select one of a (small) set of choices for an operation, or make a single choice of action. However, the USERMENU instruction is preferable for setting up the main control of your procedure; SELECT is useful when the list of choices is long or variable, or where the user can select more than one item; and DBOX offers greater flexibility.

Parameters

menu description string	either a string of text enclosed in single quotes, or a STRING variable
choice string	text displayed to identify the choice

Description

1.a MENU instruction
