    Dear all,


    Since I already received 3 different requests for this HP25-C program, here it is in enclosure.

    In my opinion checking whether it is fit (or not) for other "classical" HP Calculators (i.e. before HP28/48) should be fairly simple. The only "exotic" way of writing some of their well known functions are :

    f→R : From Polar into Rectangular
    g→P : From Rectangular to Polar
    g→H : From Decimal Degrees into Sexagesimal Degrees ° ' "
    f→HMS : From Sexagesimal Degrees ° ' " into Decimal Degrees

    This program is written in the (classical) HP calculator langage with a 4 level stack (+ Last X), probably one of the most concise and compact langages ever (but nowadays who cares about saving just one kbyte, or even just ONE byte ???, memory is virually unlimited for almost free), and I (strongly) doubt whether it can easily translated into some other different langage (TI for example ... Sorry, TI folks, we told you many times ... you should have purchased HP *** !!!)

    Best Regards to all


    Kermit


    *** I keep mischievously fueling a now almost 40 year war !!! just another 60 years to go and George and I will both like it !!!
