PERL creating variable names with other variable values.by "Peter Newton" <c-newton(at)ihug.co.nz> |
|
Hello All, Thanks for everyones responses private and on the list. I like to end the thread with a solution incase anyone searches the archives. So here it is:- ${dec."$day"} = blah blah ; the curly braces tell perl where the variable NAME starts and ends, adding the dot and the double quote marks adds the VALUE of $day to the $dec NAME. So if $day = 12; then ${dec."$day"} == $dec12; I'm also looking at arrays and hashes as an alternative. Many Thanks Peter Newton I hope I can make this question clear, I'm trying to create (using PERL) a number of variables using a loop and a count so that I can use the count value to append to the variable name like so: for ($day=1; $day <= 31; ++$day) { $dec1 = ........ blah blah; } But I want the variable $dec1 to go to $dec2 etc each time round the loop. using $day to append the appropriate digit to the variable name $dec. I've tried:- $dec$day "$dec"."$day" etc etc I'm sure I've done this before but cannot find anything. Can anyone help?? many thanks Peter Newton
