Erasing an array..
Posted by kitwalker2886 (kitwalker2886), 9 June 2007I found using the push command to fill up an array very convenient because i don ve to keep track of the array index..
but when i use the push command within a loop, the array will ve to be empty each time the loop starts or else i ll be carrying over the elements filled in the last iteration of the loop right..
As a stop gap srrangement i just used a for loop to pop out all the elements from the aray at the end of the loop.. But is there any other more elegant method to completely erase the contents of a specified array..??
Posted by admin (Graham Ellis), 9 June 2007$#listname = -1;
will clear the contents of a list called @listname
will erase a list and all its contents.
The first option leaves you with an empty list, and the second does not.
