How can the output of a compile performed via BAT file be logged?

Problem:

BAT file contains:

FOR %%F IN (C*.CBL) DO wb CHECK %%F use"new.dir"  animi >> C:\\mf\\OUT.LOG;

but the log file is always empty, what needs to be done to ensure the log file is produced?

Resolution:

Setting COBSW= s5 switch before executing the BATt file- this switch enables ANSI compatible console I/O thus allowing the log file to be written correctly
