Re: st: charlist syntax error

[Sergiy Radyakin <serjradyakin@gmail.com>]

Martyn,

alternatively there is a [closely] related command -hexstring- by me.
See instructions posted here:
http://www.stata.com/statalist/archive/2009-11/msg00726.html

It handles quotes afaik:
// ---------------------------------------
clear all
set obs 1
generate foo=`"a\`b"c'd\$e"'
list, clean noobs
hexstring foo, generate(bar)
// ---------------------------------------
          foo
    a`b"c'd$e
// ---------------------------------------

Best, Sergiy Radyakin
