Hello,

two things :
I use of stricts and warnings, and come this error
compilation when i wrote into my code.
Global symbol "$x" requires explicit package name at
./start-banco.pl line 7.
Global symbol "@word" requires explicit package name
at ./start-banco.pl line 11.
Global symbol "@bancos" requires explicit package name
at ./start-banco.pl line 17.
The compilation show there are variables globals.
What I can to resolve this problem ?
And How I can to use perldoc to read a directory and
store your names in a array ?
equal with x =`ls opt`; @word = split /\s+/, $x;
I'm bash programmer, and i want learn perl.
As Alan has explained, $x, @word and @bancos need declaring before you use
them, with 'my'.
You will also have got the message
Scalar value @bancos[$i] better written as $bancos[$i]
which is self-explanatory.
