Running Enform Plus

This section describes the initiation of an Enform Plus session, the scope of such a

session, the action of the query processor, TACL commands and macros that control and

influence the session, and the files used by the session.

The ENFORM command issued from TACL calls the Enform Plus subsystem. If no

parameters are specified, the ENFORM command appears as:

nn> ENFORM

The nn in this example represents the history number that is displayed as part of every

TACL prompt. The terminal from which the ENFORM command is entered is called the

home terminal. The syntax for the ENFORM command is as follows:

IN input-filename

specifies either the name of an Edit-format file containing Enform Plus source code

or the name of a compiled query file.

If this option is specified, Enform Plus executes the code in the specified file and

returns you to the TACL prompt at the end of execution.

If this option is omitted, the Enform Plus prompt (>) appears and you can enter

commands and statements either directly by typing them or indirectly by specifying

either the ?RUN or ?SOURCE commands. When this option is omitted, the home

terminal becomes the default input file.

OUT output-filename

specifies the name of the physical file to which output is directed. If this option is

omitted, Enform Plus directs the output to the current output listing file (described

later in this section.)

dict-subvol-name

is the name of the volume and subvolume upon which the dictionary resides. If this

parameter is omitted, Enform Plus assumes the dictionary resides on the current

volume and subvolume. Either the DICTIONARY statement or the ?DICTIONARY

command can be used to supply or change the dictionary name.

message-table-filename

is the name of the key-sequenced file containing a user-defined Enform Plus

message table. Enform Plus retrieves error and informational message text, help

message text, and/or the list of any redefined reserved words, system variables,

option variables, or command names from this file when this parameter is specified.

If this parameter is omitted, Enform Plus retrieves message text from a message

ENFORM [ / [ IN input-filename ]
