    hmm - yes - you should get something after 15 mins or so, one way or other.

    try reducing the loop counter to 32768 > 35000, just to check it works ok with that, then try upping the higher limit again.

    If only needed in a FOR NEXT LOOP you could use

    even in strings you can use it since BASIC will take the closest integer to SQR PI, hence 2.

    PRINT "HELLO"(SQR PI)
