If your screen resolution is less than 1024 x 768 or you would like to use the smaller size C-MOLD window, you can do the following. Alternatively, Windows users can easily click on the program icons with the "small" label.
$ setenv CMOLD_SMALL yes
$ source $CMOLD_HOME/cmdefs.csh
$ unsetenv CMOLD_SMALL
$ source $CMOLD_HOME/cmdefs.csh
Windows users can accomplish the same thing using the set command, although using the icon with the "small" label is usually more convenient.
