How do I get my long lines to wrap to the next line?

Answer:

Here's one way:

        CRLF=@CRLF
        Message ("Title","Line 1.%CRLF%Line 2.")
        Display (5,"Title","Line 1.%CRLF%Line 2.")

You can do it like this too:

        Message ("Title","Line 1.%@CRLF%Line 2.")

Or, here's another way:

	line1="Hello there"
	line2="GoodBye"

	Message("Test",strcat(line1,@crlf,line2))

Here's the old-fashioned way, using the built in @crlf and @tab string constants. Use the functions Num2Char or StrCat to accomplish this.

	cr=Num2Char(13) ; 13 is a carriage-return
	lf=Num2Char(10) ; 10 is a line feed
	Message("", "This is line one %cr% %lf% This is line two")

or...

	cr=Num2Char(13)
	lf=Num2Char(10)
	crlf=StrCat(cr, lf)
	Message("", "This is line one %crlf% This is line two")

Note: @crlf and @tab are explained in more detail in the WIL Tutorial section under the heading, "Nicer Messages."

How to Bring in an @crlf from the Clipboard

Question:

I want to bring in a @crlf from the clipboard and pass that onto the BoxOpen function. How do I do that?

Answer:

In the following example, "Hello %@crlf% world" is copied to the clipboard. Then we replace %%@crlf%% with two percents, so that substition doesn't happen immediately.

;Hello %@crlf% world	     ;this string (without semi-colons) copied to clipboard
param1=clipget()

param1=StrReplace(param1,"%%@crlf%%",@crlf)
count = itemcount(param1, " ")
for i=1 to count
item%i%=itemextract(i, param1, " ")
message("", item%i%)
next

;item2 is the @crlf parameter
BoxOpen('my title', strcat(item1, item2, item3))

Timedelay(5)

BoxShut()
