HISTORICAL DATA
techniques available in this GW-BASIC
language. The GW-BASIC diskette is
provided in the NCR-DOS manual.
Diskettes in these manuals contain the software you’re going to hear
so much about. In simplistic terms, software is like the old fashioned
telephone operator — it’s the middle man — you talk via the keyboard
to the software — the software via firmware communicates with the
hardware — and then comes back to you with some response. Without
software you cannot communicate with your computer. There are
several types of software:
1. System Software, e.g., NCR-DOS
2. Program Development Software e.g., GW-BASIC
3. Diagnostics Software, e.g., User Diagnostics
4. Self-teaching Software, e.g., NCR PAL and NCR TUTOR
5. Application Software, e.g., specific use programs.
