- The purpose of this program is to backup and restore files from
- a hard disk to floppy disks where the file is too big to fit on one
- floppy. The program works by copying the big file to multiple files
- where each file has a sequence number for the file type. The last
- record of the last file has an indicator that there are no more files
- to load.
- To backup a large file, enter
- A>BIGBURST TESTFILE.ASM/B
- Where TESTFILE.ASM is the large file on the hard disk and the "/B"
- tells the program that this is a BACKUP operation. The program
- will make sure the file exists on the hard disk, and as you to
- mount a floppy. It will name the file on floppy 1 as TESTFILE.001,
- file on floppy 2 as TESTFILE.002, etc until the entire file is copied.
- To restore the large file, enter
- A>BIGBURST TESTFILE.ASM/R
- Where TESTFILE.ASM is the large file on the hard disk and the "/R"
- tells the program that this is a RESTORE operation. The program
- will then tell you to mount the diskette containing TESTFILE.001.
- If you enter the wrong diskette, it will tell you to mount the
- right one. The pogram creates TESTFILE.$$$ until the entire
- process is complete. If TESTFILE.ASM already exists on the hard
- disk, it will be renamed TESTFILE.BAK and any other copies of
- TESTFILE.BAK will be deleted. When the restore is successful,
- it will rename TESTFILE.$$$ as TESTFILE.ASM, but you will still
- have the original file as a backup if neccessary.
- The only program modification required is to set the floppy disk
- drive and reassemble. It is currently set for drive D: as indicated
- in the line 'FLOPPY EQU 4'. If your floppy is on F: set that to 5,
- G: = 6, ...A:=1, B:=2, C:=3 etc. The program uses all of available
- memory as the copy buffer. For diagnostic purposes, the program prints
- out the record number just copied after copying each buffer. This
- can be removed be deleting all references to DEBUG.
