Message #18 Posted by Bruce Bergman on, 6:55 p.m., In those glory days before the personal computer, we never imagined that anyone could actually have and use a computer at home. It was (supposedly, I never doubted them though) much faster than standard FORTRAN IO. Since our applications did so much IO, the Bureau system guys wrote their own IO system that all us programmers used, called CENIO. A file for the whole US might be 100 tapes. I forget the tape density, but I think it was 6250 bpi when I left the Bureau around 1983.
#HOW TO PROGRAM TI NSPIRE UPDATE#
All of our programs were designed to read tape files, update the data with various transactions, and write back out onto tape. The Census Bureau was a huge file processing organization. But the 1108 was never as good at interactive things as it was at batch things. Those were the days! Then came the model 33 teletypes, then came the DCT interactive terminals.
#HOW TO PROGRAM TI NSPIRE CODE#
In those days, we punched our FORTRAN progam source code on punch-cards, submitted a batch job overnight to compile the program, and came back the next day to see how many errors we had. Message #17 Posted by Don Shepherd on, 5:58 p.m.,Įric, I worked on that Univac 1108 as my first programming job in 1974 at the US Census Bureau in Suitland Maryland (just outside Washington DC). There was even a "Conversational Fortran V" for it.
Your site may not have had any, but it wasn't a fundamental limitation of the computer or software. The 1108 supported interactive terminals (e.g., model 33 or 35 Teletypes, Univac DCT 500 or 100, or Uniscope 100 or 300), which could be opened as files. In response to message #15 by Don Shepherd Message #16 Posted by Eric Smith on, 5:05 p.m., In those days of mainframes only, it was all file processing. I meant interactive input with a live user.
Message #15 Posted by Don Shepherd on, 7:26 a.m., I'm 99.99% certain that FORTRAN IV on the 1108 supported input files. Hey, that's how FORTRAN worked on the Univac 1108 when I started programming in 1974! The only way to provide inputs to your program is to pass them as arguments when you run the program. TI apparently wants the NSpire to be strictly an educational tool, not a "gaming" machine with interactive inputs.Īnd we all know that INPUT serves no purpose other than games.

I hold in my hands my new HP-35s and an early version of the HP-41C that my son's university was willing to retire in my care. Message #13 Posted by Namir on, 9:19 a.m., Here is our HCC2007 programming contest (rearrange the digits of an input number into numerical order) done on the NSpire: In response to message #3 by Bruce Bergman Message #4 Posted by Don Shepherd on, 7:17 p.m., (btw, Don, I'll get back to your email shortly. So, what do the programs look like? Is it a TI-specific language? Something akin to BASIC? Message #3 Posted by Bruce Bergman on, 6:44 p.m.,
#HOW TO PROGRAM TI NSPIRE MANUALS#
Looks like TI also updated the manuals for the calculator. I just updated one OS of one TI NSpire CAS calculator, and working on updating the second one! In response to message #1 by Don Shepherd Message #2 Posted by Namir on, 12:31 p.m., It looks like they listened to those who complained. Lack of programming capability was a major deficiency of the original NSpire. The latest operating system now supports user-defined programs in addition to user-defined functions. Message #1 Posted by Don Shepherd on, 9:54 a.m. TI NSpire now supports user programs The Museum of HP Calculators
