declaring the same value for several variables. Can't Post
is there an easier way to do this:
$q01='0'; $q02='0'; $q03='0'; $q04='0'; $q05='0'; $q06='0'; $q07='0'; $q08='0';

Choose your poison:

$q01=$q02=$q03=$q04=$q05=$q06=$q07=$q08='0';

or

($q01,$q02,$q03,$q04,$q05,$q06,$q07,$q08) = 8 x ('0');

[oops: make that ('0') x 8; # thanks, japhy]

You have it slightly backwards.

<BLOCKQUOTE><font size="1" face="Arial,Helvetica,sans serif">code:</font><HR>


($you,$me,$him) = ('foo') x 3;
</pre><HR></BLOCKQUOTE>

The left operand to the 'x' operator is the string or list to be repeated, and the right operand is the number of times.

And Zeke, if you're using variables like $a1, $a2, $a3, ..., you might want to use an array instead.

<BLOCKQUOTE><font size="1" face="Arial,Helvetica,sans serif">code:</font><HR>


@array = (0) x 10;
</pre><HR></BLOCKQUOTE>

i think my preferred poison would be:
($q01,$q02,$q03,$q04,$q05,$q06,$q07,$q08) = 8 x ('0');

so to declare $q01 - $q20
() = 20 x ('0');

would that work with other variables $wrong $right etc?
