#UNDEF <constant>

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
