word worm

Word Worm is an esoteric programming language designed by User:Yayimhere and User:ais523 and named by User:int-e based on the children's game word chain

types

there are two types:

• letters which are letters in the memory (a string)
• words are all groups of letters that are separated by spaces. each word must be a valid word in English(implementation dependent dictionary)

syntax

the first line is the string memory and then there are other lines:

〈AB〉₯x

(note that A and B must be single letters) this will replace the letter A with B in the string, unless one of the words that are being replaced in is equal to x
and the special one:

《A》₯x

which will replace A with a space. if A is ' it will be deleted(both with same condition)

「x」⇒「y」

what this command does is, if the last word of the string is x then append y to the end. and dis will just delete the first word:

⇘

and this will move it to the back the program halts if one of the words in the string is not a word in english, or if no replacements apply, else it loops
word contractions will decontract(table:)
