What general tips do you have for golfing in S.I.L.O.S? I'm looking for ideas which can be applied to code-golf problems and which are also at least somewhat specific to S.I.L.O.S (e.g. "remove comments" is not an answer).
Please post one tip per answer.
S.I.L.O.S can be run here.
Abuse the preprocessor
All SILOS programs can optionally have a macro statement on the second line
Consider the following program... One of my favorite SILOS submissions by betseg.
a=97
def q print z bottle v beer L Line g wall x IntNoLine h the c around
qL 99 zs of v on h g, 99 zs of v.

Never declare variables
There is no need to declare a variable. All variables are automatgically initialized to 0.
Hence, this-
a=0
a=97
printInt a
Is the same as this
a=97
printInt a
I recently created Copy, an esoteric language, and wrote an implementation in Ruby.
The language has only 7 instructions:
copy <a> <b> <c> Copy the code block from a to b at c
remove <a> <b> Remove the code block from a to b
skip <value> Skip the next instruction if value is not 0
add <var> <v...
@HelkaHomba Yeah, ids are unique. I'll bet the room requirement is partly or mostly so that deleted or private rooms also prevent access to their messages.
@TùxCräftîñg I don't mind shameless self promotion (I even do it myself sometimes) but could you try to slow down a little? Nobody is obligated to give you votes
I would suggest refactoring the switch. This would make scaling easier
def remove_callback
@code.slice!((@i + value(line[1]))..(@i + value(line[2])))
end
...
line = @code[@i].split " "
self.send("#{line[0]}_callback")
Praming Puzles & Colf: Condense a String code-golfstring
Having spend some time on this site I have come to enjoy things being as short as possible. That may be the reason why I'm recently kind of offended by strings containing the same characters more than once. Your job is to write a function ...

@nimi @DJMcMayhem @ConorO'Brien Please don't cast regular delete votes on spam. Six spam flags do more than just deleting the post; they replace the post with a stub, lock it, and tell the system to watch out for spam from that IP.
@NathanMerrill So, it uses a strategy of dividing up the list of IDs into two buckets. Depending upon your name/your location, you only call an ID from that selected bucket. The choice of which ID to call, however, is selected by (my ID+location)%bucket.length.
When one of my bots gets switched, it can verify (based on the mover's name and my new location) whether it falls into the correct bucket, and then it can narrow down the sender's ID to one of 2 options.
Given a one digit number, return the number "flipped". Imagine it is a seven-segment display, so 2 would be:
And when flipped horizontally it would make:
Therefore when 2 is entered, the algorithm should return 5.
6 and 9 would return 9 and 6 respectively.
8 and 0 wouldn't change, so they w...
If the bot "receives a signal" (gets swapped) but his personal ID doesn't fall within the correct bucket, then the "sender" (bot whose turn it was) gets his name added to a blacklist.
So the bot can very quickly determine which names are his friends as well as narrow down the possible IDs.
I designed and implemented a custom language. After @LeakyNun refactored it to improve speed, it looks like this. I personally like it right now, but is there any more hyperoptimizations for both readability and performance.

What general tips do you have for golfing in Emotinomicon? I'm looking for ideas that can be applied to code golf problems in general that are at least somewhat specific to Emotinomicon (e.g. "remove comments" is not an answer).

In practice it probably can go up to 640k or so depending on the jvm arguments and such

I don't really understand what I can gain from Peter's comment :/
@El'endiaStarman I don't have any idea what the program does atm. It seems that it finished a while ago, but still fetches new messages. I don't have access to the system right now, so I can't stop it.
This is almost an addition to the language specifically made for this challenge. Commit by Lynn 2 days ago, challenge by @Lynn today — edc65Sep 18 at 19:59
@Dennis i dont think that should be upvoted either. but at least the built-in wasn't added specifically for the challenge (its probably the other way but point still stands).
@uoɥʇʎPʎzɐɹC think about it logically. A submission without bonuses in the negatives would mean that, for it to be present, space must be removed from the computer.
Your task is to write a program or function that takes a string as input, and prints Hello (input), I'm (language name).
Examples
Python:

etc.

Straightforward method. Repeatedly prepends the shrinking prefix until it's done.
As a bonus, it should work for non-ASCII as well.
