While the value of list can be any string of values delimited by any single ANSI value, there is a convention in BASIC+ that allows certain stored procedures to accept a list as an argument for a parameter. When that condition applies (the parameter name usually has "list" in it), the calling convention is an @FM-delimited string. To determine inclusion in the passed list, you must specify @FM as the delimiter. Only one value can be checked, for each call to InList. Returns either true (1) or false (0).
