EP_LOAD ($03) - read file from Eprom in slot 3 into RAM file

Register parameters

IN:  A = EP_LOAD
     BHL = pointer to filename (to be found on EPROM)
     IX = output file handle (to store contents of file on EPROM)


OUT: Fc = 0, file successfully moved to RAM filing system.
     Fc = 1:
          A = RC_FAIL ($16), file EPROM not available.
          A = RC_ROOM ($07), no room in filing system for data from EPROM.

Registers changed after return:
  ..BCDEHL/IXIY same 
  AF....../.... different

Notes

Before calling OS_Epr and EP_LOAD you should create a new file with an appropriate file name, using GN_Opf, A = OP_OUT. The filename to be searched on EPROM must not contain wildcards (the File EPROM is not organised as the RAM filing system). This call is equivalent to the <>EF command in the FILER. You must close the output file after the data has been copied from EPROM.

This call also works with sub file areas (a file area available on an application card in slot 3 - featured in OZ V4.2 and newer).
