Input-Control Character Clauses

END-OF-INPUT 64, 64 (3)

RESTART-INPUT "2" . (4)

The input-control character clauses are described in alphabetic order in the following

paragraphs.

ABORT-INPUT Clause

The ABORT-INPUT clause defines the characters used to terminate the processing of

the current ACCEPT statement with an abort termination status. The ABORT-INPUT

clause is recognized only by terminals operating in conversational mode.

"nonnumeric-literal"

is one or two alphanumeric characters enclosed in quotation marks.

numeric-literal

is one or two integers. Each integer must be within the range of 0 through 255.

numeric-literal is the decimal value of an 8-bit binary number.

If a process is responding in place of a terminal, SCREEN COBOL interprets the

8-bit pattern (two numeric literals convert to a 16-bit pattern) as a nonkeyboard

character.

OFF

specifies that ABORT-INPUT is not available for the current screen.

If this clause is omitted, the abort-input characters are @@.

If used, the ABORT-INPUT clause must be specified at the 01 screen level. A character

defined for ABORT-INPUT cannot be specified for another input-control character.

If the abort-input character is entered during an ACCEPT statement, no values in the

Working-Storage Section are changed by that ACCEPT statement.

(1) Documents the default field-separator character.

(2) Defines the keyboard abort-input characters as AI.

(3) Defines the keyboard end-of-input characters as @@

(ASCII code 64 represents @).

(4) Defines the keyboard restart-input character as 2.
