Screen Section

Note: This functionality is not supported in COBOL for JVM.

Screen Section Entry Skeleton
A Screen Description entry specifies the attributes, behavior, size and location for a referenced screen item which is accepted or displayed at run time.
The AUTO Clause
The AUTO clause automatically terminates an ACCEPT operation of the screen item when the last character position is keyed. No explicit terminator key is necessary.
The BACKGROUND-COLOR Clause
The BACKGROUND-COLOR clause specifies the background color of the screen item.
The BELL Clause
The BELL clause causes an audible alarm to occur each time the item containing the clause is displayed.
The BLANK Clause
The BLANK clause clears a line of a screen or the whole screen before a screen item is displayed.
The BLANK WHEN ZERO Clause in the Screen Section
The BLANK WHEN ZERO clause causes the blanking of a screen item when its value is zero.
The BLINK Clause
The BLINK clause causes the screen item to blink when it appears on the screen.
The COLUMN Clause
The COLUMN clause specifies the column at which the screen item starts on the screen.
The CONTROL Clause
The CONTROL clause allows attributes associated with a Screen Section item to be defined at run time.
The ERASE Clause
The ERASE clause clears part of the line or the screen starting at the cursor position.
The FOREGROUND-COLOR Clause
The FOREGROUND-COLOR clause specifies the foreground color of the screen item.
The FROM Clause
The FROM clause identifies the source of data for display.
The FULL Clause
The FULL clause specifies that the operator must either leave the screen item completely empty or fill it entirely with data.
The GRID Clause
The GRID clause causes each character of the screen item to have a vertical line on its left-hand side when the item appears on the screen. Each line is within the character-position.
The HIGHLIGHT Clause
The HIGHLIGHT clause causes the screen item to appear in high intensity mode when it appears on the screen.
The JUSTIFIED Clause in the Screen Section
The JUSTIFIED clause specifies non-standard positioning of data within a screen item when data is either moved to it or entered into it.
The LEFTLINE Clause
The LEFTLINE clause causes the leftmost character of the screen item to have a vertical line on its left-hand side when the item appears on the screen. The line is within the character-position.
The LINE Clause
The LINE clause specifies the line at which the screen item starts on the screen.
The LOWLIGHT Clause
The LOWLIGHT clause specifies that the field is to appear on the screen with the lowest intensity.
The OCCURS Clause in the Screen Section
The OCCURS clause eliminates the need for separate entries for repeated screen items and supplies information required for the application of subscripts or indices.
The OVERLINE Clause
The OVERLINE clause causes every character of the screen item to have a horizontal line above it when the item appears on the screen. The line is within the character-position.
The PICTURE Clause in the Screen Section
The PICTURE clause describes the length, general characteristics and editing requirements of a screen item.
The PROMPT Clause
The PROMPT clause causes the empty character positions in the screen item to be marked on the screen during an ACCEPT operation while the system is ready to accept operator-keyed data into that item.
The REQUIRED Clause
The REQUIRED clause specifies that the operator must not leave the screen item empty.
The REVERSE-VIDEO Clause
The REVERSE-VIDEO clause causes the screen item to be displayed in reverse-video.
The SECURE Clause
The SECURE clause prevents operator-keyed data from appearing on the screen.
The SIGN Clause in the Screen Section
The SIGN clause specifies the position and representation of the operational sign.
The SIZE Clause
The SIZE clause specifies the current size of the screen item.
The TO Clause
The TO clause identifies the destination of data accepted.
The UNDERLINE Clause
The UNDERLINE clause causes the screen item to be underlined when it appears on the screen.
The USAGE Clause in the Screen Section
The USAGE clause specifies the format of a data item in the computer storage.
The USING Clause
The USING clause identifies the source of data for display.
The VALUE Clause in the Screen Section
The VALUE clause specifies literal information for display on the screen.
The ZERO-FILL Clause
The ZERO-FILL clause causes trailing prompt characters to be replaced by zeros instead of spaces.
