To the first question: dont know why people do this, or do you mean that -1:

pawn Код:

if(strfind("Are you in here?", "you", true) != -1)

In this case strfind returns -1 when the string wasnt found at all, so the != -1 means "is that substring somewhere in the string?"

To question 2:
iValue = string;
wont work, this either wont compile, or will put the byte-value of the first letter of the string into iValue, and not the 250.
