LUTL
LUT Load
Class Lookup table memory management
Description Reads the lookup table having a name equal to name name from lookup table memory (or
EPROM) into the lookup table. LUTL does not re-configure the signal generating
hardware. This feature allows you to work on the contents of any lookup table memory
location, while continuing to output a signal based on a previously-used lookup table (see
LUTU command). The LUTL? query returns the location location in which a lookup table
having a name equal to name is found. If multiple lookup tables exist having name name,
then the lowest numbered location containing a lookup table with a matching name name
is returned. The lookup table memory (RAM) is always searched first. If a lookup table with
name name cannot be found anywhere in the lookup table memory, then the
industry-standard lookup tables located in EPROM (negative locations) are searched next.
LUTL? returns 0 if a lookup table with a name equal to name name cannot be found in
either lookup table space.
Command syntax LUTL name

a valid MS-DOS filename (8 characters minus any extension)
