Since you suspect the output might be truncated, have you tried to reset
ML output control by using commands given in bboard message 8?
Yes, indeed the problem is caused be truncated output.

You forgot the pair of parentheses. It should be OS.FileSys.getDir().
By the way, in order to parse a file that is not in the present working
directory you need provide the path to the file.
For example,
parse "/home/cis670/hw2/test1.mps";
