I'm not sure whether you mean a string that is defined on multiple lines or one that includes line breaks, so it displays on multiple lines, so I did both. (build as console app)

Thanks MichaelW, thats exactly what i was looking for. Is there any limit to the no. of characters can be entered. Bcoz i can enter upto a limit after that i'm getting the message that " string or text literal too long". This is not a problem i was just asking.

According to Chapter 5 of the MASM Programmer's Guide available here, under Declaring and Initializing Strings: "An initialized string can be no longer than 255 characters." The value 255 appears to be an upper limit with the actually limit depending on the form of the declaration. For a test string defined on a single line and inside a single pair of double quotes the limit was 248 bytes. Line continuations, additional pairs of quotes, and comma separators all seem to reduce the limit, by something like 2-4 bytes each.
