The following are examples of invalid syntax. These command strings would
produce an erroneous result, as explained:
LAS:MODE MDP
LAS:MODE:ILBW DEC
LAS:DIS ?
Las:LDI33;dis?
For further clarity in programming, the (Boolean) values of one (1) and zero (0)

If multiple parameters are expected, they should be separated with commas:
A query has no space between the mnemonic and the question mark:
When sending commands through the GPIB bus, the LDX-32420 uses a
terminator of <NL><^END> (new line with EOI). For users whose GPIB driver
defaults expect a carriage return in the terminator, <CR><NL><^END>, the TERM
command may be used for convenience (see TERM command in Chapter 4). For
more information, refer to your GPIB driver configuration manual.
Commands sent through the USB bus must always be terminated with new line,
<n1>.
