EDIT command

Summary

Privileges

Any user

Function

Invokes the Model 204 full-screen editor or line editor

Syntax

EDIT [({TERMINAL [SCREEN | LINE] | SCREEN [TERMINAL] | LINE [TERMINAL]})] [procnumber1 [,procnumber2 | ,procname1] | [procname1 [,procname2 | procnumber1]]

Where:

procnumber1

is the number of an existing Temporary procedure (a negative number or zero). Permanent procedure. If neither procnumber1 nor procname1 is specified, Model 204 creates a temporary procedure (0).

procnumber2

is the number of a new temporary procedure (a negative number or zero). procname2 is the name of a new procedure (1 to 255 characters); the name can contain any letters, numbers, or symbols except: Character name Keyboard display Carriage return Comma ( , ) Equal sign ( = ) Semicolon ( ; ) Single quote ( ' ) Space In addition: In version 7.6 and earlier, the procedure name cannot begin with a zero or a minus sign. As of version 7.7: Most of the above characters are permitted if CUSTOM=42 is turned on. Names containing special characters must be enclosed in single quotes for all procedure commands. See Using CUSTOM=(42) for details. The procedure name can begin with a zero. Alphanumeric procedure names can begin with a minus sign character (-), which is interpreted as a dash. For example, -1myproc and -myproc are valid procedure names. Rocket Software recommends that you limit the length of your procedure name to less than 210 bytes. Although a name in excess of 210 bytes is not incorrect and will not cause compile errors, it could be truncated by MSGCTL processing.

Syntax notes

You invoke the Full Screen Editor by entering:

EDIT (SCREEN) name

where name identifies the procedure to be edited. If this is entered from a line-at-a-time terminal, however, an error message is issued stating that a full-screen terminal is required. You invoke the Line Editor by entering:

EDIT (LINE) name

If neither SCREEN nor LINE is specified, Model 204 invokes the appropriate Editor for your terminal type.

Examples

EDIT EDIT (SCREEN) PROC1 EDIT XUPDTE EDIT -1

Usage notes

The EDIT command invokes either the Full Screen Editor or the Line Editor. EDIT can optionally specify the name or number of an existing procedure to be edited, and can specify a new name or number for the edited procedure. Specifying 0 or a negative number edits a temporary procedure. If no name or number is supplied, temporary procedure 0 is assumed.

You can invoke either of the Model 204 Editors from within a procedure and have the Editor go directly to your terminal for input. Entering the following command directs an editing session to your terminal:

EDIT (TERMINAL) procname

Model 204 selects either the Full Screen Editor or the Line Editor for the user running the procedure. The Editor reads input from the terminal until you end the session with an END, GO, or QUIT command. If END or QUIT is entered, Model 204 reads the next line of input from the procedure containing the EDIT command. If GO is entered, Model 204 reads the next line of input from the edited procedure, as if the EDIT command were followed by an INCLUDE command.

The TERMINAL option can be combined with either the SCREEN or LINE options. If an EDIT (SCREEN) command is issued from within a procedure, Model 204 displays a message that the SCREEN option requires the TERMINAL option. If an EDIT command without the TERMINAL option is issued within a procedure, the line editor is invoked. It reads editor commands from the invoking procedure. Including the TERMINAL option in an EDIT command issued from the terminal has no effect on the operation of the EDIT command.

When it processes EDIT against a permanent procedure, Model 204 ends any update unit in progress and begins a non-backoutable update unit. For more information about Model 204 update units, see File integrity and recovery.

The following tables summarize the available full-screen editor and line editor commands. In all commands that refer to procedure name (procname), a procedure number can be specified to refer to a temporary procedure. For more information, see the Model 204 editor topics.
