Many thanks Nick.
Succinct and reliable as ever.
A pity the manual is not so clear.
The limit on `wordcount- (and string functions generally)
seems to be 254 characters. Longer than that, they are silently truncated.
This does not seem to apply to local and global macros, which can be extremely long.

- -wordcount()- is subject to a limit on length of input argument. You need
. display `: word count `vars''
See -help limits- and -help extended fcn-.
