Any # entered manually are removed.
All first letters in the string are uppercased
All spaces are then removed.
The # symbol is replaced at the start.
Then the string is placed back into the string box.
This "#run program setup"
Should always be this "#RunProgramSetup

As indicated in the code header, the original masking routines are courtesy of Keya & Shardik. A little long, but
cross-platform, and easily tucked away into an include toolbox for future use.
The modifications conform to your requirements, of prefixing a hex (#), capitalising every first letter, and stripping all inline spaces. It currently accepts all alpha-numeric characters, and would capitalise characters which follow a tap on the space bar.
Hope it helps.
