White Space

White space is normally the space character (space bar). A single white space
must separate a command from its parameters or data. For example:
Okay
DELAY 500
To enhance readability, you can use one or more white spaces before a comma,
semicolon, or terminator. Since a computer normally puts the terminator at the
end of each command string (line), an extra space character at the end of the
command line does not affect the command string.
A query has no space between the mnemonic and the question mark. For
example:
Okay
TIMER?
Note: Too many consecutive white spaces can overflow the 80-byte data I/O buffer.

Terminators

A program message terminator identifies the end of a command string. These are
the valid terminator sequences:
• <NL>
• <^END>
• <NL><^END>
Many computers terminate with <CR><NL><^END> (Carriage Return - New Line
- EOI). A carriage return (<CR>) is read as a white space.
The LDC-3926 terminates its responses with <CR><NL><^END>, unless you use
the TERM command to change it. See
