CBL_WRITE_SCR_N

Restriction: This routine is supported for native COBOL only.

Syntax:

call "CBL_WRITE_SCR_N_CHATTR" using     screen-position
                                        character
                                        attribute-buffer
                                        fill-length
                              returning status-code

Parameters

screen-position

Group predefined as cblt-screen-position containing:

01 cblt-screen-position   typedef.
  03 cblte-scrp-row       cblt-x1-compx. 	*> pic x comp-x.
  03 cblte-scrp-col       cblt-x1-compx. 	*> pic x comp-x.

character

Call prototype (see Key): cblt-x1-compx

Picture: pic x.

attribute-buffer

Call prototype (see Key): cblt-x1-compx

Picture: pic x.

fill-length

Call prototype (see Key): cblt-x2-compx

Picture: pic x(2) comp-x.

status-code

See Library Routines - Key.

On Entry:

screen-position

The screen position at which to start writing. The top left corner is row 0, column 0. See Screen Routines

character

The character to write.

attribute-buffer

The attribute(s) to write. Use the following table to set one or more attributes:

B"10000000"	BACKGROUND HIGHLIGHT
B"01000000"	BACKGROUND-COLOR (RED)
B"00100000"	BACKGROUND-COLOR (GREEN)
B"00010000"	BACKGROUND-COLOR (BLUE)
B"00001000"	FOREGROUND HIGHLIGHT
B"00000100"	FOREGROUND-COLOR (RED)
B"00000010"	FOREGROUND-COLOR (GREEN)
B"00000001"	FOREGROUND-COLOR (BLUE)

fill-length

The number of screen positions to write the character-attribute pair to. If this would go off the end of the screen, the write finishes at the end of the screen.

On Exit:

None

Comments:

The blink attribute is not supported on this COBOL system. Specifying that a character is to blink results in the character being displayed with a bright background color.
