In addition to the commands described in Section III, EDIT/3000 allows you to use seven advanced commands,
as follows:
- BEGIN
The BEGIN command is used as the first expression in a BEGIN-END pair to delimit a compound
command.
- END
Terminates a BEGIN-END pair.
- NOT
Reverses the normal control, or "flag", within a BEGIN-END pair for execution of the next command.
- OR
In a BEGIN-END pair, the OR command resets the flag to true if it is false, or skips the OR command
and the following command if the flag is true.
- PROCEDURE
Calls a logical procedure written previously and stored in a segmented library (SL) for execution by
EDIT/3000.
- WHILE
Causes EDIT/3000 to repeat the next two expressions (or one if a flag is declared) until the first
expression fails (the flag is set to false) or until the SET TIME limit is exceeded.
- YES
Restores normal control within a BEGIN-END pair (resets the flag to true).
When the advanced commands are used in a logical sequence with the basic EDIT/3000 commands, they form
command blocks with recursive properties. In addition, logical procedures can be written in SPL/3000
(Systems Programming Language for the HP 3000 Computer System) or FORTRAN/3000, and these
procedures can be called for execution with the PROCEDURE command.
