- EXTENDED BATCH LANGUAGE (EBL)
-
-
-
- EBL is a command language that provides capability similar
- to the CMS EXEC languages for control of DOS functions and
- applications programs. It is self-installing-- the first
- time a batch file uses an EBL command (prefixed with "BAT")
- BAT.COM loads itself as a DOS extension where it will
- remain until the system is turned off or re-booted.
-
- With EBL greater control over the execution of batch files
- can be achieved; return codes can be consulted; information
- can be displayed on the screen or read from the keyboard;
- information that has been displayed on the screen can be
- read; a stack can be created to pass keystrokes to DOS or to
- applications programs automatically; information can be
- passed from one application to another or to DOS via global
- parameters; the presence and location of files can be
- determined and the default drive can be identified.
-
- There are two interactive demonstration/documentation files
- that enable a new user to become acquainted with EBL by
- working through them (they don't take long and you can exit
- any time.) Several more specific applications are provided
- that can also be studied to learn particular techniques.
