                                      attribute-buffer

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 to start reading at. The top left corner is row 0, column 0. See Screen Routines.
string-length The length of the string to read.

On Exit:

character-buffer The characters read from the screen. This data item must be at least as long as specified by string-length; positions in it beyond that length are unchanged.
attribute-buffer The attributes read from the screen. This data item must be at least as long as specified by string-length; positions in it beyond that length are unchanged.
string-length If the end of the screen is reached, the length read (in cells, that is, character-attribute pairs) is returned in here.
