Typo on line 30102, "SOFTUARE" instead of "SOFTWARE"

On line 30102, when examining the ticket it says "SOFTUARE" instead of "SOFTWARE". The typo appears in all three versions presented here, but not in the scans of the original source code.

Proofreading of ROLLERCOASTER-ORIGINAL.txt

I decided to sit down and transcribe the magazine version of the game myself, comparing it to yours to either correct mine or report errors in yours. I have ignored whitespace differences, as long as they are outside of strings, because they're too numerous to count. This is the result:

These look incorrect to me

• Line 11800 - "HOU TO" should be "HOW TO".
• Line 19010 is missing.
• Line 22000 uses V$ instead of VC$. Does that mean there is some graphics missing from the game?
• Line 25030 - "EVERVTHING" should be "EVERYTHING".
• Line 26010 - The parentheses are different, though it looks harmless to me.
• Line 30063 - The closing quotation mark is missing.
• Line 30200 - The "FL(1)=(2)" bit is missing from the end. That could mean you can examine the object everywhere? I haven't tried.
• Line 30490 - There's a missing space after "WITH YOU,".
• Line 40010 - How is "MID$ (VC$)I,1)" not a syntax error? Should be a comma after "VC$".
• Line 41020 - "ANSUER" should be "ANSWER".
• Line 47005 - The text on this line is quite garbled.
• Line 48010 - "PRIZES!" should be "PRIZES:".
• Line 48050 uses V$ instead of VC$. Missing graphics?
• Line 54020 - In the original, it's two sentences. Not one.

I assume these are the minor fixes mentioned

• New REMs on lines 0, 21999, and 40000
• Line 10800 - I assume the extra space between "THINGS," and "AND" is to make the text spill over nicely to the next line.
• Line 22084 - The single PRINT has been split into two. Not a bad idea, but this is the only place I saw that done.
• Line 30073 - The double space between "SALVAGEABLE." and "A GUARD" has been changed to a single. For consistency, I assume.
• Line 30101 - A missing single quote has been added.
• Line 30200 - Spaces have been added, presumably to make the text look better.
• Line 31000 - I assume "D^" actually means CTRL+D, so changing it to CHR$(4) seems fine.
• Line 34055 - An extra space between "PARK" and "WITH" has been removed.
• Line 47000 - Spaces have been added after "UNLESS YOU".
• Line 48010 - Similarly to line 31000, "G^" has been changed to CHR$(7). Seems ok to me.
• Line 48060 - The missing "POSTER" has been added.

Bugs in the original

• Line 22050 should probably add "F1=0", so that "DOESN'T EXIST" is printed for rooms with no exit.
