Back in the late '80s, I worked for a guy who had written a program in the Procomm Plus (serial datacomm software) scripting language to collect status data from a group of about 200 network interface devices (Sytek 2502 boxes).
He had a separate loop to collect and store each parameter.
All 53 of them.
It took almost all night to run (if I remember, this was on an IBM PS/2 Model 60, under DOS 3.3), but at least it was ready the next morning for his BASIC program, which summarized and formatted the data and printed a report.
I rewrote the Procomm script into one loop, and it finished in about an hour.
