Thank you, Ben and Seb. I went through my code, removed several quote
marks and can now make a graph with -twoway `scatter'-. I had assumed
that string macros must be enclosed in quotes, like this:
. local str "a b c"
In the code that runs without error message, I create the string
macros without quote marks.
. local str a b c
Is this still official Stata? All examples in [P] macro use quotes
around the strings.
