ExecHex: det(14); Ans = hex code

Executes the string of ASCII-encoded hexadecimal in Ans. Although a C9 (ret) at the end of your hex string is highly encouraged, Celtic will automatically put one at the end for safety regardless. For a list of useful hex codes, refer to this page.

Ans must be under (not including) 8192 characters. It also must be an even number of characters.

Parameters:

  • Ans: hex code to execute.

Returns:

Errors:

  • ..INVAL:S if there is an invalid hex digit or an odd number of characters in the string.

Note

If you use the alternative method and use 0 for os_color, it will invert the section of the screen covered by the rectangle instead of drawing a color. This can be useful for blinking cursors, etc.
