MANUAL FOR RELOCN (6502 assembler)

This file describes the program RELOCN which moves a given file down in 
memory after it has been loaded so that it can run where the DFS workspace
used to be.
The manual is (C)1997 SPROW and software is (C)1996 SPROW

INSTRUCTIONS-
At the BASIC prompt,type CHAIN"RELOCN" or whatever you've saved it as.

The program will pose you with some rather blunt questions,the answers to
which should be as follows:
1.Assemble at
  This is where the final,resulting file will be loaded in at.For a DFS system
  it should therefore be above &1900 on a BBC B or &1B00 on an Econet machine.
2.Filename to relocate
  This is the place where the source file is
3.Execution address
  You'll need to find out where this is from the source file.After the program
  has been relocated this is the address that will be jumped to.
4.Relocation address
  This is where the source file will be shifted down to.So a file from the 
  cassette filing system might move to &E00.

Example session
         *OPT 1,2
         *CAT               and you'll see something like
         <filename>         <block#> <load addr> <exec addr> <length>
         Myfile             0F       00000E00    00001234    00000F99
where 'assemble at' might be &1E00
      'filename' is "myfile"
      'execution address' is &1234
      'relocation address' is &0E00
