Incorrect result to input checking in GameMaker

Question

Message for MHS readers: Do not copy this code. Just use it for help with yours.

I have 10 words loading from a file and then 9 are displayed in a grid. After 30 seconds 1 is removed and the 10th word from the file is put in. The user is then asked to guess these 2 words. They have 3 chances for each. When I enter the correct answer it still says I got it wrong. I even have it draw the correct answers to assist in testing. The result always comes back false.

These are the scripts: ReadFile

global.DelWord = "Unknown";
randomize();                                                               
Fopen = file_text_open_read(working_directory + "\Words.txt");    
global.WordList = ds_list_create();
global.FileLen = file_text_eof(Fopen);
while(!file_text_eof(Fopen)){
    Fread = string_upper(file_text_readln(Fopen));
    ds_list_add(global.WordList,Fread);
    }
file_text_close(Fopen);
ds_list_shuffle(global.WordList);
global.WildCard = ds_list_find_value(global.WordList,global.FileLen);
ds_list_delete(global.WordList,global.FileLen);

Answer 1

You used file_text_readln() for read words from file, but this function also reads CR/LF codes ($0d, $0a), so when you compare two strings, like

ABOUT (ASCII codes: 97, 98, 111, 117, 116)

and

ABOUT (ASCII codes: 97, 98, 111, 117, 116, 13, 10)

it will return false.

Therefore you need change

Fread = string_upper(file_text_readln(Fopen));

to

Fread  = string_upper(file_text_read_string(Fopen));
file_text_readln(Fopen);
