Sure you are. Lattice had no IDE; it was strictly command-line
driven--if the input required a text editor, it was up to you to furnish
one. If the MSDOS hosting system used a BIOS, fine. But not all did.
Consider the MSDOS platforms that interfaced to a simple serial
terminal. In any case, console and file I/O is done via the DOS API.
How DOS does things is no concern of the compiler.
This is the way before fancy screen I/O that we did things. Before
that, it was with punched cards.
