Programs written in long form are easily read and are
almost self-documenting. Using short form commands
conserves the amount of controller memory needed for
program storage and reduces the amount of I/O activity.
The rules for creating short forms from the long form is
as follows:
The mnemonic is the first four characters of the key-
word unless the fourth character is a vowel, in which
case the mnemonic is the first three characters of the
keyword.
This rule is not used if the length of the keyword is
exactly four characters.

You can use upper or lowercase letters
Program headers can be sent using any combination of
uppercase or lowercase ASCII characters. Instrument
responses, however, are always returned in uppercase.
Combine commands in the same subsystem
You can combine commands from the same subsystem
provided that they are both on the same level in the
subsystem's hierarchy. Simply separate the commands
with a semi-colon (;). For example, the following two
lines,
OUTPUT 720;":CALC2:PEXC 12"
OUTPUT 720;":CALC2:PTHR 20"
can be combined into one line:
OUTPUT 720;":CALC2:PEXC 12;PTHR 20"
The semicolon separates the two functions.
