Mar 6, 2021 at 23:39 comment added Cloudy7 @MartinEnder I just realized, looking at this a year later, that a significant number of bytes could be shaved off here, as you can obtain the value -1 by parsing a string without a number in it at Parsons Green to obtain 0, then using Notting Hill Gate to turn it to -1. This would remove the need to use Cannon Street entirely. Also, there are a couple station names that could be reduced -- "Embankment" can be replaced with "Bank", for instance.
Apr 22, 2020 at 16:12 comment added Martin Ender @Cloudy7 Yeah, you're right, I meant Cannon Street.
Apr 22, 2020 at 16:07 comment added Cloudy7 @MartinEnder Wow, that's still better than what I dreamed up, which was getting the name of the station "Bromley-by-Bow", getting the last seven characters at Mile End, using Charing Cross twice to get the hyphen out, then concatenating with a string containing a number at Paddington. (Interestingly, Notting Hill Gate seems to add 1 to any positive integer and then negate it. Weird.)
Apr 22, 2020 at 9:40 comment added Martin Ender @Cloudy7 Yeah something like that. I just stepped through the program in the Esoteric IDE, and apparently I picked up the 7 from Seven Sisters, divided by itself in Chalfont & Latimer to get a 1, negated in Notting Hill Gate to get a -2 and added those together in Upminster for a -1. In hindsight, this seems a little unnecessarily complicated. I think I could've just done the last two steps to the input (without picking up the 7, or dividing by itself).
Apr 22, 2020 at 1:09 comment added Cloudy7 Minor question - how did you store -1 in Hammersmith? I'm thinking of doing the same for a program I'm writing. I'm guessing it was by Notting Hill Gate, but I could be wrong.
