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.
