Is there a function that will look through a string and if it contains another string it will return true. For example, lets say you had a string

Global Str$ = "My name is Bob."

and you want to know if it contains the string "Bob". How would you do that.

Thanks

Instr$()

Wow, that's it? Great, I forgot about that function, thanks.

Str.Contains( "Bob" )

Contains Returns true if a string contains subString

Oh, I think that looks more like it. Thanks jsp.

But it can't find the function Contains().

jsp	(Posted 2007) [#7]

Global Str$ = "My name is Bob."
Print Str.Contains( "Bob" )
Print Str.Contains( "BMAX" )

run it to see the result

EDIT: And it is a Method not a Function

OOP, errr.

Thanks though.

Take a look in the help at Language->Strings this lists all the methods available for strings.

Dont forget the find method if you want to know where the sub string is:

Local str:String = "My Name is Bob"
Local pos:Int = str.Find("Name")

How could I <????> the Character at a Position of a String?

One vital word missing from your question. Anyway, look for right$, left$, mid$ if the missing word is 'find'.

Sorry, yes I meant find. What is the syntax of those commands?
I need to return a single character.

Local str$ = "hello"

Print Chr$(str$[4])
'..or..
Print str$[4..5]

What is the syntax of those commands?

Type, for example, 'right$' in the IDE and press F1 for syntax. Press F1 again for the command reference.
