HP 9800 Series Desktop Computers - HPL Description

HPL Description

In HPL instead of variables such as A1 and J2, there were numbered registers r1, r2, up to r199999. This HPL program for the HP 9825 generates a list of prime numbers:

0: fxd 0 1: prt 1 2: prt 2 3: 1→P 4: for C=2 to 1000000 5: P+2→P 6: for N=3 to P/3 7: if int(P/N)*N = P; gto 4 8: next N 9: prt P 10: next C

Another unique characteristic of HPL was the right arrow (shown with ASCII characters as ->, however it was a single character). This arrow was known as the gazinta (slang for "goes into"). The statement 1→P would be pronounced "One gazinta P".

Famous quotes containing the word description:

    The Sage of Toronto ... spent several decades marveling at the numerous freedoms created by a “global village” instantly and effortlessly accessible to all. Villages, unlike towns, have always been ruled by conformism, isolation, petty surveillance, boredom and repetitive malicious gossip about the same families. Which is a precise enough description of the global spectacle’s present vulgarity.
    Guy Debord (b. 1931)
