RE: Witango-Talk: ARRAY??

Hi Gene and Dave,

Thanks for the snips. They both work well. Unfortunately, I already have gotten this far. I understand how to assign and filter arrays.

Maybe I should explain myself more fully...

It's not the values I am concerned about, but the naming of individual variables in ascending order. I need the final result taken out of the array and put into individual variables named whatever1, whatever2, whatever3 and so on with no variables being empty. So in your example. I would nee variables with no null variables named spaced1, spaced2 spaced3 and so on.

Example

(original array)
A (row1)
B (row2)
C (row3)
   (row4)
   (row5)
D (row6)
E (row7)
   (row8)
F (row9)
   (row10)
G (row11)
H (row12)

(what I need)
<@ASSIGN spaced1 "A">
<@ASSIGN spaced2 "B">
<@ASSIGN spaced3 "C">
<@ASSIGN spaced4 "D">
<@ASSIGN spaced5 "E">
<@ASSIGN spaced6 "F">
<@ASSIGN spaced7 "G">
<@ASSIGN spaced8 "H">

The reason I need these variables named this way is because I am going to pass them as hidden arguments to an ASP program that writes out a business card. Now it would look funny if the cards had blank lines in them. Yet I need to name the cells in Acrobat specifically for each line on the card. So if a person wants their name, address and email but not there phone or fax, the args passed would go to the top cells.

Business Card Cells on original card

____Name_________(Named spaced1)
_____Address1_____(Named spaced2)
_____Address2_____(Named spaced3)
_____City, State Zip_ (Named spaced4)
_____phone________(Named spaced5)
_____fax__________(Named spaced6)
_____email_________(Named spaced7)
_____cell__________(Named spaced8)
_____route________(Named spaced9)
_____whatever_____(Named spaced10)

would turn into...
____Name__________(Named spaced1)
______Address1_____(Named spaced2)
______Address2_____(Named spaced3)
_____City, State Zip__(Named spaced4)
______email________(Named spaced5)
______(blank)_______(Named spaced6)
______(blank)_______(Named spaced7)
______(blank)_______(Named spaced8)
______(blank)_______(Named spaced9)
______(blank)_______(Named spaced10)

Is this making sense???

Another way to do the same thing would be to use the filter tag:

<@Assign Local$SpacedArray <@ARRAY VALUE="A;B;C; ; ;D;E; ;F; ;G;H;">>
Spaced Array Begins as = <@Var Local$SpacedArray><p>
<@Assign local$SpacedArray <@filter array=local$SpacedArray
expr="len(<@trim str='#1'>)">>
Spaced Array now = <@Var Local$SpacedArray><p>

   Sure. Here's sample code. I've tested it, it works.

<@Assign Local$SpacedArray <@ARRAY VALUE="A;B;C; ; ;D;E; ;F; ;G;H;">>

Spaced Array Begins as = <@Var Local$SpacedArray><p>
<@Assign Local$RowCount <@Numrows Array=Local$SpacedArray>>
<@Assign Local$Ptr 1>

<@FOR START="1" STOP="<@Var Local$RowCount>">
        <@IFEMPTY VALUE="<@Trim Str=<@Var
Local$SpacedArray[<@Currow>,1]>>">
        <@ELSE>
                <@Assign Local$SpacedArray[<@Var Local$Ptr>,1] <@Var
Local$SpacedArray[<@Currow>,1]>>
                <@IF EXPR="<@Currow>!=<@Var Local$Ptr>">
                        <@Assign Local$SpacedArray[<@Currow>,1] ' '>
                </@IF>
                <@Assign Local$Ptr <@Calc EXPR="<@Var Local$Ptr>+1">>
        </@IF>
</@FOR>
Spaced Array now = <@Var Local$SpacedArray><p>
<@Assign Local$Ptr <@Calc EXPR="<@Var Local$Ptr>">>


<@Comment>Delete Remaining blank rows in the Array</@Comment>
<@FOR START="<@Var Local$Ptr>" STOP="<@Var Local$RowCount>">
        <@Delrows Array=Local$SpacedArray>
</@FOR>
Spaced Array now = <@Var Local$SpacedArray><p>


Hope this helps!

Hey Gene,

I have been trying to wrap my arms around this one. Do you have a
simple example you could show/send me? For some reason the second
loop never counts.

Also,

is it possible to do this using the <@for> tag?

Thanks for any help.

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.

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
