A <program mnemonic> is a command or command path identifier. For example, the <PROGRAM MESSAGE>
"LAS:IncN consists of the command "Inca and the path ide- "LA!Y. All ofthe legal <compound command
program headere
may be traced by starting from the root node of the command structure and moving down by
levels to paths, and finally to the command (see Figure 4.2).
A <PROGRAM MESSAGE TERMINATOR> causes the next mmmaxul search to begin at the mot node. A
leading colon
(:) on a <PROGRAM MESSAGE UNTP will cam the LDC-3700 Series Laser Diode Controller to
begin searching for the command at the root node. Otherwise (after a semicolon), the LDC-3700 Series Laser
Diode Controller
will first search the most recently used node for the command It will continue to search the
command
tree until it finds a legal command path, by searching each previously used node up to the root. If no
legal path is found, the LDC-3700
Series Laser Diode Controller will generate an error message. For more
information on creating and
using LDC-3700 Series Laser Diode Controller commands, see Section 3.5, Advamd
Programming.
Parameters (and other <PROGRAM DATA,) may be entered after a command in a <PROGRAM MESSAGE
UNIT>. The <COMh4AND PROGRAM HEADER> (command) and !kt <PROGRAM DATA UNIT>
