This function releases PRIVATE variables
__mvRelease( <skeleton>, <include_exclude_flag> )
<skeleton> = string that contains the wildcard mask for variables’ names that will be released. Supported wildcards: ‘*’ and ‘?’ <include_exclude_flag> = logical value that specifies if variables that match passed skeleton should be either included in deletion (if .T.) or excluded from deletion (if .F.)
This function releases values stored in memory variables. It shouldn’t be called directly, it should be placed into RELEASE ALL command. If the released variable is a PRIVATE variable then previously hidden variable with the same name becomes visible after exit from the procedure where released variable was created. If you access the released variable in the same function/procedure where it was created the the NIL value is returned. You can however assign a new value to released variable without any side effects. PUBLIC variables are not changed by this function.
