May I suggest a solution? Introduce another variable called Ptr. Initialize it to one. Walk through your loop testing each element for values. For examining array fields for nulls I typically use <@Trim Str="<@Var...
Now, if you do NOT find the array element empty increment Ptr by one. As long as the array elements have valid values Ptr will keep pace with your look counter. When the first empty spot is detected both counters will be the same. At the bottom of the loop you test to see the array element pointed to by your loop index is empty. If not, test to see if loop index and Ptr are the same. If so, do nothing. If not, assign the element pointed at by your loop variable to the location pointed at by Ptr and empty the element pointed at by your loop counter. Then increment your loop counter and Ptr. When you run across an empty cell, with your loop counter, you do not increment Ptr. This will collapse all of the empty space out of your array and condense it at the end of your array. It is complicated to explain but very easy to do. A small loop and a couple of if statements. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Wednesday, July 21, 2004 4:20 PM To: [EMAIL PROTECTED] Subject: Witango-Talk: ARRAY?? Okay, I'm tired and crabby and need help. This should be simple, but for some reason, I am just not seeing it. I have variables that I am populating with small amounts of text. They are named ... <@VAR lcell1> = test1 <@VAR lcell2> = <@VAR lcell3> = test3 <@VAR lcell4> = test4 etc. etc. etc. Let's just stop at 4 for now to keep this simple (simple is good! Good simple) Now I created a loop and a counter that counts up to 4 and I have added this in the loop... <@IFEMPTY <@VAR 'lcell<@VAR l_counter>'>> <@ELSE> <@ASSIGN NAME="llcell<@VAR l_counter>" VALUE="<@VAR 'lcell<@VAR l_counter>'>"> </@IF> And when I display the results I can see the values correctly. It is working as expected BUT I would like to skip the counter on every <@VAR lcell that is empty. I other words, If <@VAR lcell2> is empty, move the values from <@VAR lcell3> into <@VAR lcell2> and also move the values from <@VAR lcell4> into <@VAR lcell3>. Is this making sense? I would like to get all the variables named 1, 2, 3, 4 etc. with no empty variables between. The final result should be a list of numbered variable that contain no empty variables or empty variables in the end... Original Variables... <@VAR lcell1> = test1 <@VAR lcell2> = <@VAR lcell3> = test3 <@VAR lcell4> = test4 Modified Variables <@VAR llcell1> = test1 <@VAR llcell2> = test3 <@VAR llcell3> = test4 <@VAR llcell4> = Thanks There's gotta be an easy way to do this ________________________________________________________________________ TO UNSUBSCRIBE: Go to http://www.witango.com/developer/maillist.taf ________________________________________________________________________ TO UNSUBSCRIBE: Go to http://www.witango.com/developer/maillist.taf
