Writes a string of characters and their attributes to the screen.

Restriction: This routine is supported for native COBOL only.

Syntax:

call "CBL_WRITE_SCR_CHATTRS" using     screen-position
                                       character-buffer
                                       attribute-buffer
                                       string-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-buffer
Call prototype (see Key): pic x (n).
Picture: pic x (n).
attribute-buffer
Call prototype (see Key): pic x (n).
Picture: pic x (n).
string-length
Call prototype (see Key): pic x (n).
Picture: pic x (n).
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-buffer The characters to write.
attribute-buffer The attributes to write.
string-length The length of the string to write. 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.
