Removes variables from memory.
DropWild ( variable/wildcard )
(s/a) variable/wildcard: variable or wildcarded variable.
(i) number of items dropped.
Note: a wildcarded variable does not recognize a wildcard at the beginning of the variable name. DropWild only accepts a wildcard on the end of the variable name, i.e. "var*".
This function removes variables from the WIL Interpreter's variable list, and recovers the memory associated with the variable (and possibly related string storage).
A variable is defined the first time it appears to the left of an equal sign in a statement. It stays defined until it is explicitly dropped with the DropWild function, or until the current invocation of the WIL Interpreter gets closed.
Generally speaking: in batch file-based implementations of WIL, all variables are dropped automatically at the end of every batch file; and in menu-based implementations of WIL, variables stay defined until explicitly dropped.
Drop and DropWild can accept array names as parameters.
Note: WIL is limited to 2000 variables.
Warning: Do not attempt to use the wildcard "*". This causes unpredictable results.
a1= "A variable"
a2= "Another variable"
DropWild("a*") ; This removes A1 and A2 from memory
