Can anyone tell me how to SET a string from a text file in DOS. I need to run this in a batch file. The file contains just one line e.g. Calculated TTF CRC: 00B2 If i can set a string to the data in the file, i can then extract the last 4 digits using the "%string:~n" to extract the CRC.

To get the string into a variable (as you want it) this might work: :: Code begins.... @echo off cls for /f "delims=*" %%A in ('type string.txt') do ( set string=%%A ) echo %string% :: Code ends.... To immediately extract the crc try: :: Code begins.... @echo off cls for /f "tokens=1-4" %%A in ('type string.txt') do ( set crc=%%D ) echo %crc% :: Code ends.... Whichever way you choose - good luck.

Sure, but not in DOS. ===================================== If at first you don't succeed, you're about average. M2
