stregex question [message #67222]

I'd like to find the first "e" in a string that is not next to
another "e"

The solution
stregex(s,"e[^e]|$") ;"e" followed by not "e" or at the end of the
line
doesn't work for the string st = 'see me' because it will find the
second "e" in "see"

The soluton
stregex(s,"e{1}") ;Find one occurrence of "e"
also finds the first "e" in "see" (Two occurrences is also one
occurrence)

In Perl it seems that one would use the "lookahead" option, but that
doesn't seem to be available in stregex().

(Actually I am looking for the first quote that is not part of a
double quote, but I wanted to keep the example syntax simple.)
Thanks, --Wayne
