C64 ROM: Routine at FFBD

Used by the routines at E1D4, E219 and E257.

this routine is used to set up the file name for the OPEN, SAVE, or LOAD routines. The accumulator must be loaded with the length of the file and XY with the pointer to file name, X being th low byte. The address can be any valid memory address in the system where a string of characters for the file name is stored. If no file name desired the accumulator must be set to 0, representing a zero file length, in that case XY may be set to any memory address.
