Command Interpreting Processor

When a terminal or batch job is initiated under SINTRAN III, it is first connected to the Command Interpreting Processor (CIP) which reads each command line from the terminal or batch input device, checks its validity, and performs the requested action. After a particular command is executed, or when a user program or subsystem terminates, the control is returned to the CIP.

The prompt for the CIP is @ character. During a terminal session, the prompt is printed to indicate that the previous action is terminated and that SINTRAN III is ready for a new command. Note: the @ character should not be typed by the user.

When submitting batch jobs, or reading commands from other devices than the terminal, all commands must start with the @ character to recognize them as commands.

A command is a string of characters separated into words by a comma or by a number of spaces. The first word is the command name, followed by a parameter words if necessary.

In batch jobs the command name and all parameters must be contained on one line or card. In the terminal session missing parameters will be requested by the CIP.

Certain parameters may take a default value which will be used if the parameter word is omitted, by giving the comma separators or by responding with a carriage return when the parameter is asked for.

Command names and parameter words may be abbreviated by giving sufficient characters to distinguish it from other permissible values. A special character, the - is used to separate words in two or more distinct parts. any part may be abbreviated as long as it doesn't become ambiguous
