It would come back pretty quick if you ever had to use it.I like it!
My first major programming job was in Fortran and it involved re-writing a program that had been originally written onto punch-cards, and when printed onto 132 column fan-fold it came out to about 1500 to 2000 sheets. I was tasked to re-write it so it would run on a more modern computer. It had a routine that did a huge amount of number crunching but using a base 11 numbering system.
There were two comments in the entire suite of software. I recall them distinctly...
Comment If there is a tape input error the printer will print 100 pages of # characters. That will stand out like dogs balls.
Comment The following routine uses a base 11 numbering system. If you cant work that out get another job.
The bloke that write the software had moved on and was only available for assistance at consultant rates and when his new employer allowed him to take calls so I was pretty much on my own.
The base 11 routine would have been about 500 pages in its own right I estimate.
Then it struck me - just use Hex. That's built in so I don't need an external routine.
I used to live and breath hex and binary Kosh.
Not now. I have forgotten almost everything I ever knew.
Everm modern stuff,we were trying to interface an older micrologix plc to a touchscreen hmi a few weeks ago and couldn't get it to work properly to save ourselves, turned out the micrologix plc stored its words in registers arsed aBout, ie lsb was msb..
