in the place where you increment $num do you re-assign $line? $num++; ## this changes only $num $line=$array[$num]; # this changes $line to the new index that $num is now.
if you don't do the second line then $line will still be $array[whatever $num was before] you need to reassign $line to the new line. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Tuesday, March 05, 2002 10:06 AM To: [EMAIL PROTECTED] Subject: accessing an array with a variable Hi, I believe it is possible to access an array through a variable, but I'm ghaving trouble doing it. I want to read in a text file and display it, on line at a time, depending on an increment counter triggered by a 'next' or 'previous' button. I am trying to do this with Perl/Tk, but it fails to work, only displaying the initial line of the text file: This is the definition of the variable $line=$array[$num]; $num is incremented elsewhere with the click of the button. This is the attempt to display the variable on screen. $txtmain->configure(-textvariable => \$line, .....); I know that the incrementing is successful because replacing $line with $num as the -textvariable gives the right output. Any help would be greatly appreciated.
