Finding a word in a file

Say i have a word which i want to look up in a file, how would i do this. Im sure its very simple but i have looked at the command reference and in the code archive.

Can anyone help?

Here is something to get you started:

find$="sublicense"
txtfile$="textdoc.txt"

file=ReadFile(txtfile$)
If file
	flag=False : lcount=0
	While Not Eof(file)
		l$=ReadLine$(file) : lcount=lcount+1
		pos=Instr(l$,find$)
		If pos>0
			flag=True
			Print "Found ["+find$+"] at position "+pos+" in line "+lcount
		EndIf
	Wend
	CloseFile file
EndIf

If flag=False Print find$+" not found in "+txtfile$
a$=Input$("Press RETURN to end")
End

I used the above on this text file called 'textdoc.txt'

Thanks very much! :) It looks a bit confusing but i am starting to work it out. Thanks again!!!!

Seems a long-winded way of doing things. Here is another way to do it...

name$="Blitz Basic"
find$="it"
location = Instr( name$,find$,1)
Print "Your string contains '"+find$+"' at position number " + location

This is assuming that the file is loaded into a string.
