How to output str variable as text?

[Scott_Y]

Noobie here, non-programmer.
Please help me understand my error in this macro. It is intended to produce the current date with format 2014-0303. Thank you!

Code:

Copy      Help

str s
s.timeformat("{yyyy-MMdd}")
s             ;; output date as 2014-0405

The error message says
Error in yyyy-MMdd: syntax.

-------
EDIT: Ok, now I realize that the error is in the third line. So my new question is "How can I output the formatted date (or any string variable) as text?"

-------
EDIT 2: Got it (condensing the last two lines into one):

Code:

Copy      Help

paste s.timeformat("{yyyy-MMdd}")
