Instruction Manual Revision 3.11
5-3
The instrument will always send the response data in capitals. Headers are not sent in the
response messages, only the parameters.
5.2.4 Long and Short Form
Program messages may be sent in either long or short form.
♦
The long form is the full word
♦
The short form is usually the first four characters of the long form
The short form in a syntax specification is shown in upper case, and the remaining part of the
long form is shown in lower case characters.
Note : Upper and lower case, as used in syntax specification, is only a notation habit to facilitate
distinction between long and short form. The instrument itself does not differentiate between
upper and lower case characters.
In program messages, either the long or short form may be used in any mix of upper or lower
case characters. There is no semantic difference between upper and lower case in program
messages.
