Change directory of lst and obj files

Hi

I wish to change the directory where the lst and obj files are created using the command line arguments [PRINT and OBJECT]. I wish to keep the output file names same as the input files.I tried invoking the C51.exe from the CommandPrompt and use PRINT[../lst/*.lst] as directive and i get fatal error "file cannot be created".

I guess there is a way to this from a batch file,could some one show it how exactly that goes about?

Thanks
