[ale] Off topic - perl question

[Zhongbin Yu " <zyu at premtec.com>]

I did split(/\./, $test) and it worked fine.

'man perlfunc' gives sympnosis of split as the following:
	split /PATTERN/,EXPR,LIMIT
	split /PATTERN/,EXPR
In regular expression,  a single dot is reserved char. It acts more like a
wild card, it stands for any character. w is alphanumeric plus _, and d is
for number. So, need use \ to espace it.

$0.02.

## this works fine so it is the period that is causing the problem but

#@fi = split (/"."/,$test);

#@fi = split (/"\."/,$test);
