-------Commodore Trivia Edition #30 Questions and Answers Preface--------
Not to leave you in the dark for too long, here are the trivia
answers to the previous edition of Commodore Trivia. I am posting the
answers at this time, and will post the scores and winners in a few
days. This time frame is set up to allow time for any discussions on the
correctness of these answers. By this time, the newest edition of
trivia has been posted. I encourage you to enter it.
This edition of trivia answers has been posted to the USENET newsgroups:
comp.sys.cbm, alt.folklore.computers, and comp.sys.amiga.advocacy. It
has also been posted to the FidoNET CBM Echo.
Feel free to use these trivia answers in newsletters, magazines, and other
publications (please see disclaimer). If you use the trivia, I would
appreciate knowing where it has ended up. If you intend to use this
information, please wait a few days after the posting date to allow for
major errors to be corrected.
Please mail any new questions for upcoming trivia (with answers) to my
address.

I try to post the answers for the questions shortly after the monthly
contest has ended. However, I usually wait a few days for any errors
I may have made to be worked out before scoring the contest.
-------Commodore Trivia Edition #30 Questions and Answers (BEGIN)--------
The "BASIC" Trivia Set
Q $1D0) To load a program from the current location on a cassette tape, what
two key combination must a user press on a VIC-20 or C64.
A $1D0) SHIFT and the RUN/STOP key. Note that the same key sequence loads
a file from disk on the SX-64 or C128 in 128 mode.
Q $1D1) If I issue the BASIC statement OPEN "JIM,S,W", What type of file
am I opening?
A $1D1) A sequential file.
Q $1D2) Is BASIC in the Commodore computer systems an "interpreted" or
"compiled" language
A $1D2) interpreted. When a program has been "Blitzed!", it is then
compiled.
Q $1D3) What type of variable is A%?
A $1D3) An integer variable.
Q $1D4) If I issue the BASIC line PRINT:PRINT "A","B" what column does
the "B" show up on when run on a C64?
A $1D4) Column 11, if we number columns from 1.
Q $1D5) What column does "B" show up on if I run the BASIC line in $1D4 on
a VIC-20?
A $1D5) Column 12. Since the VIC has 22 columns, the natural column spacing
was 11 positions, instead of 10 on 40 and 80 column CBMs.
Q $1D6) Alphebetically, what is the first BASIC 2.0 command to have a 3
letter abbreviation?
A $1D6) CLOSE.
Q $1D7) How many times does the statement FOR T=1TO0 execute?
A $1D7) once. A BASIC for loop always executes at least once. This is
different from languages like 'C', which would not execute the loop
at all. Feature or bug, who knows...
Q $1D8) What base does the BASIC LOG command use for its logarithm
function?
A $1D8) base e. (2.7....) (one of the entrants claims that "e" in the 64
isn't quite as accurate as we think. He was quoting 2.85....
Q $1D9) A = NOT B can be written as which expression:
a) A = -B
b) A = -(B+1)
A $1D9) b. NOT computes the twos-complement of the number, not the simple
ones-complement negation. This feature simpleifies subtraction in a
CPU, since subtractions can be performed as additions.
Q $1DA) What does INT(-15.43) return?
A $1DA) -16. INT returns the next LOWER integer.
Q $1DB) What does ASC$("JIM") return?
A $1DB) ASC$ returns an error. That's what I get for writing these late
at night. What I menat was "ASC", returns the value of the first
character of a string, in this case 'J'. Since I didn't specify
if this was a uppercase 'j' or lowercase 'J' in graphics mode, the
result could either be 74 or 202.
Q $1DC) What is the abbreviation for GET#?
A $1DC) Technically, there is none. However, on the C128 at least, GET#
shares the same token as GET, so typing gE# will indeed work.
This is different from PRINT and PRINT#, which have different
tokens.
Q $1DD) What is the largest integer value that Commodore BASIC can handle?
A $1DD) Again, this was a little ambiguous. I was looking for the maximum
value that an integer variable can hold, which is 32767, but line
numbers (which are integers) can be up to 63999.
Q $1DE) What is the ONLY Commodore Editor key not affected by "quote mode"
A $1DE) The DEL key. I would have answered return, but the 64 PRG spells
it out that only this key is unaffected.
Q $1DF) What is the range of RND?
A $1DF) 0.0 <= RND < 1.0, or [0,1). Both mean that the range is from 0 to
1, including 0, but not 1.0.
