In Windows the blank blocks are indicated by being highlighted or not. On the command line it will say "Memory Blank" after execution.

I think the OP wanted to get a DOS ERRORLEVEL value, which he could check in a bat file.

FM.exe should return 1 for error and 0 for success, which I believe is used to set ERRORLEVEL.
