How to change .ESL Icon using good 'ol native FoxPro 2.x

Copy and past the code below into a .PRG file, I like to call it FIXICON.PRG, but that is up to you. You will need to change the name of the Icon file (as designated by the .ICO file name) in line 17, and the path to your .ESL file in line 19. Then, compile, and run, and like magic, you'll have a new Icon that represents your overall application, and that silly Fox Head will disappear.
Note: That I don't recommend using Icons that are greater than 16x16, or that use High Color definitions. FPW was created back in the day before such things, and I have had *unusual* (at best) experiences with icons over 256 colors, or 32x32.
Make sure you back up your .ESL file before applying this Icon code. (You never know what might happen...)
