AS400_RPG_Examples
The example in here is an interactive report program written in the (long dead) AS400/RPG programming language.
It was used by the planning department in a textile mill to run what-if manufacturing scenarios. The user input SKUs and requested quantities to weave and received a report back detailing pounds of yarn required vs on-hand quantities and weeks to weave figures.
RPG is of course no longer relevant in today's world; but, it is something I taught myself after being offered a job that required it and I am proud of this particular program as it takes advantage of some of the languages more advanced techniques (Multiple-occurrence data structures, free format code blocks, etc.)
