The SCREEN function returns the ASCII code of a text character or the color attribute at a set text location on the screen.


Syntax: code% = SCREEN (row, column [, {0|1}])


  • Row and column are the text coordinates of the SCREEN mode used.
  • Colorflag omitted or with a value of 0 returns the ASCII code of a character at the position designated.
  • When Colorflag is greater than 0, the function returns the color attribute used.
  • Color values returned may not be correct in screen modes other than SCREEN 0.


Example: Reading the ASCII code of a character, then the color used.

row = 10
column = 10
code% = SCREEN(row, column, 0) ' character code return
attrib% = SCREEN(row, column, 1) ' character color return
