- COMAL Corner #9
- ===== ====== ==
-
- by: Joel Ellis Rea
-
-
- Hello! WOW, was July ever a month
-
- to remember! Particularly that last
-
- weekend. From Thursday the 25th to
-
- Monday the 29th, I was in King of
-
- Prussia, PA. in the Sheraton Valley
-
- Forge Hotel and Convention Center, at
-
- the MARCA Fair. I met wonderful
-
- people, saw wonderful things, and had
-
- a wonderful time. I'll tell you more
-
- about it in 2 articles this month, one
-
- for the COMALites and one for general
-
- interest readers.
-
- Once again, there's a summary of
-
- the weekly Thursday night "Let's talk
-
- COMAL" get-togethers on PlayNET
-
- ("COMAL PlayNotes"). This issue
-
- covers the month of July. Because of
-
- the Fair, I couldn't "attend" the
-
- July 25 meeting.
-
- As for programs, how about Conway's
-
- Game of Life? It is written in 0.14,
-
- but is LISTed to disk so it can be en-
-
- tered into 2.0. It is COMAL Kernal-
-
- compatible (assuming C64 text screen),
-
- so no conversion is needed to enter it
-
- into Version 2.0 (cartridge). This
-
- version of Conway's Life is unique in
-
- that it uses the 64's Color Nybble
-
- memory to keep track of how many
-
- "neighbors" each cell has. This re-
-
- sults in a visible effect on the
-
- screen as the program performs its
-
- calculations! Be SURE to read the
-
- ABOUT text before RUNning it!
-
- There is no COMAL Tutor installment
-
- this issue. Next issue's installment
-
- will introduce the single most
-
- powerful aspect of COMAL: Subprograms
-
- (PROCedures & FUNCtions)! We will
-
- convert our CELSIUS program into a
-
- FUNCtion, make another FUNCtion to
-
- convert from Celsius to Farenheit,
-
- and a PROCedure to get input from the
-
- user!
-
-
- Well, that's all for this month.
-
- If you have a modem, be sure to sign
-
- up with PlayNET and come see me in the
-
- COMAL room every Thursday night
-
- starting at 9:30 Eastern Time.
-
- Captain COMAL will usually be there
-
- as well!
