FMTL <name>
Limits: <name> = a valid MS-DOS filename
(8 characters minus any extension)
Description: The FMTL command reads the format having a name equal to name <name> from format
memory (or EPROM) into the format register. FMTL does not re-configure 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.
FMTM <first> <last> <destination>
Limits: <first>, <last>, <destination>
1 thru 300 (RAM)
Description: The FMTM command moves formats in format memory beginning with location <first > and
continuing thru location <last> to another area of memory beginning at location
<destination>. Source and destination areas may overlap, but may not be the same. Non-
overlapping source locations are zapped (erased) after formats have been moved. To leave
the source locations intact, use the FMTD command instead of this one.
FMTN
Description: The FMTN command initializes the format editing register. Sending this one command is
equivalent to sending all of the following commands:
ASBG ø XVSG 1, 1, 1 GAMA 2.2 SCAN 1
ASCT 1 CSPG 1 GAMC ø SSST 1
ASGG 1 CSPP ø HRAT ø USIZ 2
ASSG ø, 1, 0 DCBM ø HRES ø VRES ø
ASSS ø.286 DSEX ø HSIZ 280 VSIZ 210
AVPG ø DSST 1 HSPD ø VSPD ø
AVPS ø.ø DVSP ø HSPG 1 VSPG 1
AVSB ø.ø DVST ø HSPP ø VSPP ø
AVSS ø.714 EQUA ø HSPW ø VSPW ø
AVST ø EQUB ø HTOT ø VTOT ø
This should be the first command sent to the generator when downloading a new format.
The command only resets the register to a known state. The command does not create a
usable format. After the FMTN command has been sent, the commands FMTB, HRAT,
HRES, HTOT, VRES, VTOT, VSPW, AVST (or DVST), and FMTE must be executed before the
new format is used, otherwise a format error will result.
FMTQ? <index> <number>
Description: The format pointer query reads in a knob list of formats starting at <index> and will read in
<number> of format names. Used to read knob lists.
FMTR <location>
Limits: <location> = 1 thru 300 (RAM) or -1 thru -24 (EPROM)
Description: Read format from the format memory location into the format register. The FMTR command
does not re-configure the signal generating hardware. This feature allows the contents of the
format register to be worked on, while a signal, based on a previously used format,
continues to be output (see FMTU command). The FMTR? query returns the <name> of the
format stored in location <location>. FMTR? returns the string “EMPTY” if the format
memory location <location> is empty.
