Class
Memory Variables
Purpose
Stops text substitution for a constant created with #DEFINE
Syntax
#UNDEF <constant>
See Also
#DEFINE, LOCAL, PRIVATE, PUBLIC
Description
The #DEFINE command is used to define FoxPro compatible constants. Constants declared using #DEFINE can be overridden by a memory variable of the same name, but cannot be modified or manually released after their initial declaration. Constants are automatically updated if the value of <exp> changes and are released on exit from the session. The #UNDEF command stops the text substitution for a constant created with #DEFINE
Example
#DEFINE NEXT_LOOP for I = 1 to NEXT_LOOP ? i next #UNDEF NEXT_LOOP
