C64 ROM: Routine at FFD8

Used by the routine at E156.

this routine saves a section of memory. Memory is saved from an indirect address on page 0 specified by A, to the address stored in XY, to a logical file. The SETLFS, FFBA, and SETNAM, FFBD, routines must be used before calling this routine. However, a file name is not required to SAVE to device 1, the cassette. Any attempt to save to other devices without using a file name results in an error. NOTE: device 0, the keyboard, and device 3, the screen, cannot be SAVEd to. If the attempt is made, an error will occur, and the SAVE stopped.
