Hi,
I am trying to do a balnk check first before I program P89C664, anyone know what is the return variable from FM command to indicate whether the device is blank or not?
rdgs,
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.
