How to check if clipboard has a null string or a space " "?

[Johnc]

10 | IF | CLIPBOARD | VALUE | TEXT IS | ENDMARKER | STOP

The above line worked well to check if the CLIPBOARD contains the string "ENDMARKER".

What should I put down instead of "ENDMARKER" if I need to check if the CLIPBOARD contains a NULL string or a space?

Please advise Steve. Thanks!

For a space:
3 | IF | CLIPBOARD | VALUE | TEXT CONTAINS |   | MESSAGE PROMPT | clipboard contains a space value::%clipboard%
By a 'NULL' string are you referring to the clipboard being 'nothing', having no value?

oic, this is how to do it for a space " ". Thanks Steve! Yes, what is the character to use for nothing? ""??
Actually I need the macro to stop running when the current line in a text file it is cutting and pasting from is empty.

It now works when I put a "token word" there like "END" but I am hoping that I don't need to do that.

e.g.

The text in the notepad file: (now working)

john
peter
joe
END

I am trying to do the same thing without using END:

john
peter
joe


another list here
mary
carol
june

Hopefully the macro would stop after processing joe coz there is a blank line after joe.


Thanks!

Have you considered using a FOR LINE IN loop:

- d:\macro\names.txt
john
peter
joe

mary
carol
june

1 | FOR | EACH | LINE IN | D:\Macro\names.txt | DO
2 | IF | STRING VARIABLE | %LINE% | IS |  | STOP
3 | RUN ACTION |  |  |  | MESSAGE PROMPT | Value of the line: "%line%"::Names
4 | FOR |  |  |  | NEXT

This macro will STOP (line 2) when it gets the blank line after joe and before mary.
Line 2 checks for "" no value in the current LINE. If you take the delims out it looks like this - IF STRING VARIABLE LINE IS STOP. Notice that there is no value after the 'IS' text option.

Yes, I should give FOR loop a try but it might be harder to keep track of where the loop is at the moment.
