FMTL
ForMaT Load from memory by name
Class Format memory management
Description Assigns a format to the current step of a sequence while between a set of SEQB and
SEQE commands. The FMTL command is context sensitive. The FMTL? query returns
the name of the format currently assigned to the step.
Outside of the sequence editor, the FMTL command reads the format having a name
equal to name from format memory (or EPROM) into the format. FMTL does not
reconfigure the signal generating hardware. This feature allows you to work on the
contents of any format memory location, while continuing to output a signal based on a
previously used format (see FMTU command). The FMTL? query returns the location
location in which a format having a name equal to name is found. If multiple formats exist
having name name , then the lowest numbered location containing a format with a
matching name name is returned. The format memory (RAM) is always searched first. If a
format with name name cannot be found anywhere in the format memory, then the
industry-standard formats located in EPROM (negative locations) are searched next.
The FMTL? query returns zero if a format with a name equal to name cannot be found in
either format space.
