Purpose
Return a number according to the menu item chosen
Syntax
MENU TO <memvar>
See Also
@...MENU, COL(), MENU AT, MENU COMMAND, MENU FIELDS, MENU FILES, MENU FORMAT, MENU QUERY, MENU SCOPE, READVAR(), ROW()
Description
The MENU TO <memvar> command returns a number from 1 to n, according to the menu item selected, and zero if [ABANDON] was pressed. The companion command is @<expN>,<expN> PROMPT "item" MESSAGE "text".
The READVAR() function may be used to return the current <memvar>.
The MENU TO <memvar> command starts at the <memvar> position within the range of 1 and the number of @…MENU items defined in the menu.
The COL() and ROW() function may be used to return the coordinates of the current MENU TO <memvar>.
These commands are supported for compatibility with other products. It is far better to use @…MENU…COMMAND for this purpose.
Example
@10,10 prompt "edit"; message "edit a record." @11,10 prompt "append"; message "add a record." @12,10 prompt "delete"; message "delete a record." menu to choice do case case choice=1 do editfunc() case choice=2 do appendfunc() case choice=3 do deletefunc() otherwise dialog box "No choice." endcase
