Hello everyone, I think I have found a bug in 'convert/pjson'.
load 'convert/pjson' dec_pjson_ '"\\f\\b"' \ \ I believe double backslashes should be escaped first, as in: dec_pjson_ '"\\f\\b"' \f\b I fixed the issue on my end by moving the double backslash to the first substitution: ESC=: _2[\('\';'\\';CR;'\r';LF;'\n';TAB;'\t';(8{a.);'\b';FF;'\f';'"';'\"';'/';'\/') As opposed to ESC=: _2[\(CR;'\r';LF;'\n';TAB;'\t';(8{a.);'\b';FF;'\f';'"';'\"';'\';'\\';'/';'\/') Thanks ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
