Look up the values of named global variable var in the file named fileName and modify the named flag flag.
lookup(var, fileName, flag)
var - type: str
fileName - type: str
flag - type: str
Old-style, slated for overhaul. For most purposes, we recommend using the spellword function to see if something is a dictionary word.
This is a highly specialized word lookup. Global variable var has multiple words as values (assumed to be alphabetically sorted and unique). fileName is a file of strings, one per line. flag tells which bit-flag of the word's symbol table entry to modify. See also the unknown function.
The code lookup("Words", "dict.words", "word") looks up all the values in the Words variable in the dict.words file and modifies the word bit-flag (which says whether the word is a proper English word).
