Hello, We have an MCS-30 with a 3.5 floppy drive. But we cannot copy programs to it if the program names are longer than 8 characters. Does anyone know how to change this to a higher number? Thank you.

That documentation was written 20 years ago and was meant to be a reference for the software. To use autoprogram...engineers would take a 3-5 day class. It simply was not supposed to be learned from a manual.
