cecho | Self-adapting color echo wrapper for shell | Command Line Interface library

I want to recursively search a folder for all exe files and have the batch script automatically set each program.exe file found as a user choice input. It needs to auto-populate the choices appropriately and stop when the last exe is found. So if there are a total of 8 exe files in the searched folder then it would auto output set /p choice of 8 programs.exe's to choose from. Not 9 choices and not 7. The exact number of choices needs to be accurate for all found matches. This is an attempt to streamline the coding process.

I have a massive script I made that will auto populate up to 6 found exe files. There lies my problem. I am capped. The script works well for what it is but I am hoping someone has a trick up their sleve and a new way of thinking about the code execution. I won't lie when I say that this script I made is a bit of a mess. Thanks in advance to anyone who might have some ideas.

Important note: I downloaded and exe program called cecho.exe that helps colorize the terminal output text. I highly recommend using it if you want to debug my script. It would be a giant mess without it. Stick cecho.exe in your system32 folder or whever you want as long as it can be accessed with out needing the full path to the file.
