It turns out that this time it works with AND without an equal sign in
the local marco command.  I am really confused.  Is there any explanation
why STATA does this?  Is there a general rule for using equal sign or not
in the local marco command?

Thank you very much!

What Stata are you using? As pointed out on p. 202 of the Stata 9 users Guide, if you use the = sign, strings are limited to 244 characters in Stata/SE and 80 characters in Intercooled and Small Stata. Your string is more than 80 characters. If you skip the equals sign, you can go several thousand characters (how much depends on what Stata you have.) So, it is better to not use the equals sign.
