Is it possible to search a string for an empty line? And return a true or false value?

Example 1 (has empty line):

"HELLO MY
NAME

IS CHRIS"


Example 2 (does NOT have empty line):

"HELLO MY
NAME
IS CHRIS"

Yes it is.

Use:

-Find(string$( "String" ), NewLine$+NewLine$, 0)

Where "string$("String")" is the string you're testing.

It will return -1 if there are no empty lines.


However this method only detects empty lines within the content.
To detect a empty line on the end of the string:

-Compare two general values
right$(string$("String"),1) <> newline$

Thanks UrbanMonk!

I've been experimenting and it seems Find(string$( "String" ),"your search here" , 0) will return the character value.

For example, here is a string:

Handgun Bullets
Lighter
Instant Coffee


Find(string$( "String" ), "Lighter", 0) will return a value of 17. The word "Lighter" begins at the 17th character in the string.

Is it possible to retrieve a line number instead?
