in thread Why do here-docs have to end with a newline, not EOF?

Really? I can reproduce the OP's results on WinXP and Linux.

WinXP, Perl 5.8.8, ActivePerl 820

>perl -e"print qq{print <<ENDHERE\nabc\nENDHERE}" > test.pl >perl test.pl Can't find string terminator "ENDHERE" anywhere before EOF at test.pl +line 1. >perl -e"print qq{print <<ENDHERE\nabc\nENDHERE\n}" > test.pl >perl test.pl abc >

Linux, Perl 5.8.4

$ perl -e'print qq{print <<ENDHERE\nabc\nENDHERE}' > test.pl $ perl test.pl Can't find string terminator "ENDHERE" anywhere before EOF at test.pl +line 1. $ perl -e'print qq{print <<ENDHERE\nabc\nENDHERE\n}' > test.pl $ perl test.pl abc $

If I were to guess, I'd say the parser looks for <"\nENDHERE\n"> instead of <"\nENDHERE" followed by either "\n" or end of file>, and it does so because it's easier and because every line is suppose to end with a line feed in unix.

    perl -Te 'print map { chr((ord)-((10,20,2,7)[$i++])) } split //,"turo"'
