Hi everybody! I have to make a batch program that will give a choice to the user: press enter to restore or escape to backup Those are the only two keys usable. How do I make this program. I tried with set/p and errorlevels, cant do it. Can anyone help? Thanks!

The following batch solves your assignment, but I doubt you can get any help from it @echo off set de=ASK.TXT type NUL > %de% echo.AAAAAAAAAAAA> %de:~0,-4%.COM :: [Assembly_By_Debug] echo.N %de:~0,-4%.COM>>%de% echo.A 0100>>%de% echo.MOV AH,08>>%de% echo.INT 21>>%de% echo.CMP AL,00>>%de% echo.JNZ 010A>>%de% echo.INT 21>>%de% echo.MOV AH,4C>>%de% echo.INT 21>>%de% echo.>>%de% echo.W>>%de% echo.Q>>%de% :: [End_Of_Assembly] debug %de:~0,-4%.COM < %de% > NUL Echo. echo. [ENTER] for RESTORE echo. [ESCAPE] for BACKUP echo. :LOOP %de:~0,-4%.COM if %errorlevel% equ 13 goto :RESTORE if %errorlevel% equ 27 goto :BACKUP goto :LOOP :RESTORE echo.RESTORE goto :END :BACKUP echo.BACKUP goto :END :END del %de%.* set de= :: [End_Of_Batch]

Thanks IVO it works! BUT... What does this mean? echo.AAAAAAAAAAAA> %de:~0,-4%.COM My best guess would be echo AAAAAAAAAAA in the file called %de at position 0 -4%.com????

Also where can I get more information about how to use debug and all of those echo a,echo n, etc functions? thanks

See response number 1 for all your programming information... forums usually work best when the proper protocols are followed There is no such thing as Health Food... just Health Fanatics!

To illy About the DEBUG command take a look at http://technet.microsoft.com/en-us/... The statement echo.AAAAAAAAAAAA> %de:~0,-4%.COM creates the file ASK.COM of lenght 14 bytes (12 As and a CR/LF), exactly the size Debug produces assembling ASK.TXT. You can't write the contents of memory without a file equal or greater to the interval to be saved. The %de:~0,-4% is the substring from %de% with the last four position stripped away. To know about type Set /? at prompt. The echo sequence creates the text file to be interpreted by Debug: it declares the file to be modified (N), codes the instructions (A), saves them (W) and quits (Q). the statement debug ASK.COM < ASK.TXT > NUL forces Debug to read its commands from ASK.TXT, to suppress the output messages (redirected to NUL) and to operate on the ASK.COM file. The script can be less cumbersome but I coded it just on the fly. To Ewen, you are right, but despite its (apparently) complexity what posted is just a plain batch and many scripts of this kind are hosted in this Forum. My way is to help first of all.
