Re: Windows testing/debugging

Probably somewhere in MSDN.

The problem is not in Perl, the problem is in Windows command line where 
single quote is not a quote, and double quote should be doubled (or 
escaped) to work as people from bash/sh world would expect.

Examples:

C:\>perl -M5.010 -we "say ""a"""
a

C:\>perl -M5.010 -we "say "a""
Unquoted string "a" may clash with future reserved word at -e line 1.
Name "main::a" used only once: possible typo at -e line 1.
say() on unopened filehandle a at -e line 1.

C:\>perl -M5.010 -we 'say "a"'
Can't find string terminator "'" anywhere before EOF at -e line 1.

C:\>perl -M5.010 -we "say \"a\""
a
