Rothbrg - Woodbridge, Ct 11/18/81 :History of UNERA For the last few years I've been looking for a 'restore' or 'unera' type program to forgive my errors. I found it in the December '81 issue of Interface Age. If you don't subscribe, you should ! :Info The following is excerpted from the IA article The safest and most reliable method of guarding a disk file is to have a back up copy. Often in the fever of creation we forget. Sometimes we even go to 'clean-up' our work disk, and in error type A>ERA *.BAS When what we meant was: A>ERA *.BAK So now we're in big trouble, we've just erased the last four hours, or days, of work. What to do ? To the rescue, comes UNERA ! The UNERA.ASM program is written to run on an 8080, 8085 or Z80 (registered tmark of you know who) microprocessor. To use UNERA, look over the source file and change it for CP/M 2.2 or 1.4 as required. Check the disk translate table to be sure it is correct for your disk system. Change if necessary. Assemble UNERA Load ERA Then TRY it on a scratch disk ! :Command format In order to use UNERA you MUST know the name of the file(s) to reclaim/ restore/un-erase. A>UNERA D:FILENAME.EXT Will bring back into existance the file D:FILENAME.EXT that you erased in error. For limitations on files that may be un-erased, see the writen article in IA, 12/81 page 98. You may have problems un-erasing a file if you have created new files since you erased it. The CP/M operating system may have re-used the disk space where your erased file is/was. Test the un-erased file to insure that UNERA worked properly. You must give the disk drive when specifing the file to be un-erased, or the software assumes drive A, not the logged in drive ! :Version info UNERA.HLP Help file version 1.1 As of 11/18/81 Henry B.
