I have a static map of the game that the player can find and view. What is the easiest way to implement this so that the player can press "m" from anywhere in the game to view the map, and then be returned to his original location when done viewing?

Legend of Rhovanion (a game every mzxer should play imho) had a system work just like this, but there are other and more modern ways to do it. LoR just had a board that had the map on it and 'm' saved the board and player coordinates, teleported you to it, and then back. I can only imagine it worked something like this:

end
: "keym"
set "P_X" "playerx"
set "P_Y" "playery"
set "$BOARD" "BOARD_NAME"
teleport player "MAP" 0 0
end

. "........... and to get back"
end
: "keym"
teleport player "&$BOARD&" "P_X" "P_Y"

You could also try using a sprite while on the current board using an MZM on the Vlayer. This would work something like this:

. "This just initializes the sprite"
put "@MAP.mzm" Image_file p02 0 0
set "spr255_vlayer" 1
set "spr255_static" 1
. "worth noting that this makes the map stick to scrolledx/y regardless of where the player is."
set "spr255_refx" 0
set "spr255_refy" 0
set "spr255_overlaid" 1
set "spr255_width" "MAP_WIDTH"
set "spr255_height" "MAP_HEIGHT"

. "to put the map at the viewportx/y"
end
: "keym"
put c?? Sprite pff 0 0
. "0 0 in this case is relative to the viewportx/y, it will just be in the upper left corner"
wait 1
zap "keym" 1
end

. "to make it go away"
end
: "keym"
set "spr255_off" 1
wait 1
restore "keym" 1
end

You could also use the following, instead of saving coords and board name:

end
: "keym"
save player position 1
teleport player 'MAP' 0 0

and to return:

end
: "keym"
restore player position 1

I find this working a bit better and more efficient in code to use than saving the coordinates and board name seperately. This command does it all at once.

(Or did I miss something that causes this to no longer work? If so please correct me)

save/restore player position works fine, the only downside is that restore player position uses a fadeout/fadein which you may not necessarily want, especially if you want to incorporate your own transitions. But it's certainly a lot simpler and avoids certain problems that can arise from the other approach such as issues with having multiple boards with the same name.

Yeah, to make that more consistent, you can just have it do a color fade out/in before and after the teleport. The waits are important.

. "put this in the global somewhere"
color fade out
wait 1
save player position
teleport player "map" 0 0

. "@menu robot"
wait 1
color fade in
wait 1
. "loop"
restore player position
end

Thanks for the tips. The save/restore position works great.
