#################################

Golf64 with Course Selector is an add-on to Golf64 to make it easier to select a specific course.
It basically does nothing more than set up the «C=RND(-n)» for you that you otherwise would have to type in.


Task and Goal
=============
see Golf64


Control (Selection Screen):
===========================
press 1-9 on the keyboard to select the course
press <space bar> -or- fire button (Joystick port 1) to play course

see Golf64 for in-game control


Game Requirements:
==================
- C64/C128* with BASIC 2.0 runtime environment (or compatible)
- 1 Player

*Also playable on Windows/MacOS/iOS/Android (C64 Emulator required)


Starting in VICE: C64 emulator (http://vice-emu.sourceforge.net/):
==================================================================
Start the emulator and then drag and drop the "golf64cs.prg" into the VICE window.
-or-
Load the program with the command: load "golf64cs.prg",8
Then start the program with:       run

Tip: Copy/paste the program-Code into CBM prg Studio (http://www.ajordison.co.uk/).
There you can see the commands in nice color highlighting and you can directly execute the game in an emulator of your choice.


Variables used in the code (lines 10-19)
========================================
a  = angle (also used as temporary variable to call the rnd(-l) function)
a$ = key pressed (as string)
g  = distance from teeing green to hole
g$ = string of g value (to lign the number up nicely)
i  = only used in the for/next loop
j  = 197 (zeropage address containing the last pressed key - already assigned in line 0)
p  = par number
l  = selected course number

for lines 0-9 see Golf64
