In a command prompt (or in a batch file), imagine your program is called crc32.exe
and it is called like this
crc32.exe filename.ext
and it displays
filename.ext : 1293640
(or whatever the crc is suppoesed to look like)
you would redirect the output to a file, eg
>$TempCRC$ crc32.exe filename.ext
then read the file into a variable
Set /P MyCRC=<$TempCRC$
now %MyCRC% contains
filename.ext : 1293640
You can use string operations to remove the unwanted bits and have just the crc value
easy really -- but the example I gave was for a mythical crc generating program, you will have to experiment with a real one (or several) until you get the results you need
