In general; they produce object code. The compilers have to take
advantage of object-specific features that are not available via the
assembler syntax.


The Dignus compilers produce assembler, and we have to provide our own
assembler that not only is IBM compatible, but also has support for
these features.


And, due to the various complexities of IBM assembler syntax, it's
frequently the case that the compile step is much faster than the
assemble step.
