FORTRAN77 on a VAXCluster in 1986.
Still have my copy of "FORTRAN 77 For Engineers and Scientists" just in case.
It was very easy to pick up for someone who had only used AppleII or TRS-80 BASIC.
- acidburnNSA 7y agoI'm still using a program and occasionally updating it that's mostly in FORTRAN 77. Originally written in FORTRAN IV. Ah, gotta love the nuclear industry. Good code though.
- waynecochran 7y agoI used to have Fortran77 notepad for hand writing code — later I would type it in. Always began in the 8th column if I remember right?
- username223 7y agoYep -- old-school fixed-format Fortran had one column for the "c"(omment) marker, seven for the statement number (maybe 5 plus spaces on either side?), then 72 for the code before you fell off the end of the punch card.
- drfuchs 7y agoNo, you get all 7 spaces for the statement number; live it up a little! Don't know if it's still the case, but in FORTRAN IV you don't need spaces between keywords and variable names. So when the compiler sees "FORI=2" it has to look still further ahead to decide if this is a for-loop (FORI=2TO9DO) or an assignment to a variable named FORI. Decidedly not a context-free grammar; you can't even figure out the tokens without the ad-hoc parser getting involved.
