pre {-a} {-f} {-m} {-o} filename

opre {-a} {-f} {-m} {-o} filename

The pre and opre commands are equivalent to the A-Shell command programs of the same name, and are pre-compilers calling into the AlphaBASIC 1.4 and AlphaBASIC 1.3 compiler respectively. The only difference in operation is that the command line switches, instead of appearing in upper-case after the program name (e.g. /A), are given in lower-case with a hyphen before it. This is analogous to the way all UNIX commands function.
