General Command Information
The following are general guidelines for using the Parser:
1. All commands begin with either a colon (:) or an asterisk (*).
2. The Parser has a tree structure. In order to access commands lower on the
tree or on a different branch, enter the entire command string.
3. There should not be any spaces between levels of the command string (like a
DOS directory).
4. The Parser is case-insensitive (it does NOT care about capitalization). The
user can either enter all capitals, all lowercase, or a mixture. (The examples
use all capitals only for clarity.)
5. Either the entire command word given in the tree or the abbreviation (the
capitalized letters in the tree) can be used.
6. There should be a space between the command string and option. The
exception is a query, which ends with a question mark (?).
7. Most commands have a query form. The optional question mark (?) can be
used after almost any command string to find out the present state of the
SPG 422. There is NOT a space between the command string and the
question mark.
8. Most commands have a help function. Typing “help” after a command string
will list the commands available at that level. There is a space between the
command string and the word “help”.
9. Enter more than one command on a line by using a semicolon (;). There is
NOT a space between the command string and the semicolon. This is
especially useful for echoing back any changes made.
If the semicolon is separating commands from the same branch of the Parser
Tree, it is not necessary to re-enter the entire command string after the
semicolon.
If the two commands are from different branches of the tree, there is no
shortcut. Enter the entire string.
