I believe you can use this:

pos = FIND SUB STRING$(source$, substring$)

It returns a negative number(or so it seems) if the substring isn't in source$.

TDK_Man has a function library that has a bunch of functions that do stuff with strings. I know he has a function that finds a word. Go here and download the String function library.

This is one of those "huh" messages. You want to find the word "how" from one string and put it in another string.

To find a word you must know the word.

If you already know the word there's no need to do anything special to put that string in another word. Benjamin told you all you need to know. Use that to determine if the word your looking for is in the string... if it returns a number less than 1 then it's not in the string.



I suggest also to change the string you looking in to highercase and the string your looking for to highercase. That way it won't fail the search if you look for words with mixes of highercase and lowercase letters.

do the same thing again with the other word?

To find same word multiple times simply keep finding the word;

The set of functions that UFO mentioned includes one which takes a sentence and returns all the words in an array, along with the number of words found.

You can then use the number of words variable a simple For...Next loop to check if the word you are looking for was in the sentence.

Grog Grueslayer already gave you the code to find a word and Me! has already suggested doing exactly the same code but using a different search word.

We could post the code you need but if you can't even fathom out how to do such a simple task you will never learn. Should take you less than 30 seconds to get it working.

We weren't being angry but actually trying to be helpful.

It would be pointless simply posting the code to do everything you want because it sounds like you haven't the foggiest idea how simple variables work.

You already know how to detect if a sentence contains a special word, so just repeat the command again using a different word and use a different variable to store result, for example you could use 'a' like now, to see if 'how' is in your sentence and 'b' to see if 'is' is in your sentence. Then you could say something like;

if a < 1 and b < 1 then neither word exists
if a > 0 and b < 1 then only word 1 exists
if a < 1 and b > 0 then only word 2 exists
else both words exist

Have a go at incorporating that.

I hope that if this is for someone else to play, you get a dictionary out before it's released!

Oy!

Quote: "so pleas fix this code "


Just look at what input string you use and what string your looking at with the "find sub string$" command. You need to use the strings that have been defined instead of strings that don't exist yet (until you use them for the first time).
