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.

Warning

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

Note

When executing the hex code, the bytes are executed at the address $D0547A in memory, or pixelShadow2 + 436.

Parameters:

  • Ans: hex code to execute.

Returns:

  • Runs the specified hex code.

Errors:

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

FillRect: det(15, low, high, x, y, width, height)

Draws a filled, colored rectangle on the screen.

Parameters:

  • low: low byte of color.

  • high: high byte of color.

  • x: x location to draw the rectangle, beginning at the top-left corner.

  • y: y location to draw the rectangle, beginning at the top-left corner.

  • height: Height of rectangle.

Alternative method: det(15, os_color, x, y, width, height)

  • os_color: Color from TI-OS Colors menu, like RED or BLUE or NAVY.

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.
