Thank you for replying to my questions.
After playing around with this '/e' modifier with s///, I do have a question which I cannot solve now:
$AGE = 17;
$text = 'I am $AGE years old'; # note single quotes
$text =~ s/(\$\w+)/$1/eeg; # print I am 17 years old
$text =~ s/(\$\w+)/$1 * 2/eegx; #I tried to double the age, but faile
+d
How I can double the age in s/// format for the above code as showed by a similar but different example:
$text = "I am 17 years old";
$text =~ s/(\d+)/2 * $1/eg; #now I am 34 years old
Thank you.
