OP jaytea Fjord artisan J Joined: Feb 2006 Posts: 546	i've noticed an apparent bug when using $regsubex() inside another $regsubex()'s subtext parameter: Code: $regsubex(12345,/(\d)/g,X $regsubex(\1,/\d/,x) \1) = X x 1XXXX the first round of substitutions works out alright (same happens with \t too) but the rest seem to be treating that inner $regsubex() and \1 as null the expected result would be of course X x 1X x 2X x 3X x 4X x 5 "The only excuse for making a useless script is that one admires it intensely" - Oscar Wilde
