Instruction Header
The instruction header is one or more command mnemonics separated by
colons (:). They represent the operation to be performed by the
oscilloscope. See Chapter 8, “Programming Conventions,” starting on page
129 for more information.
Queries are formed by adding a question mark (?) to the end of the
header. Many instructions can be used as either commands or queries,
depending on whether or not you include the question mark. The
command and query forms of an instruction usually have different
program data. Many queries do not use any program data.
