Mom file creation (5 product limit) - loops

Question

Ok, I realize this is a very niche issue, but I'm hoping the process is straight forward enough...
I'm tasked with creating a data file out of Customer/Order information. Problem is, the datafile has a 5 product max limit.
Basically, I get my data, group by cust_id, create the file structure, within that loop, group by product_id, rewrite the fields in previous file_struct with new product info. That's worked all well and good until a user exceeded that max.
A brief example.. (keep in mind, the structure of the array is set by another process, this CANNOT change)
orderArray = arranyew(2);
set order = 1;
loop over cust_id;
field[order][1] = "field(1)"; // cust_id
field[order][2] = "field(2)"; // name
field[order][3] = "field(3)"; // phone
field[order][4] = ""; // product_1
field[order][5] = ""; // quantity_1
field[order][6] = ""; // product_2
field[order][7] = ""; // quantity_2
field[order][8] = ""; // product_3
field[order][9] = ""; // quantity_3
field[order][10] = ""; // product_4
field[order][11] = ""; // quantity_4
field[order][12] = ""; // product_5
field[order][13] = ""; // quantity_5
field[order][14] = "field(4)"; // trx_id
field[order][15] = "field(5)"; // total_cost
counter = 0;
loop over product_id
field[order[4+counter] = productCode;
field[order[5+counter] = quantity;
counter = counter + 2;
end inner loop;
order = order + 1;
end outer loop;
Like I said, this worked fine until I had a user who ordered more than 5 products.
What I basically want to do is check the number of products for each user if that number is greater than 5, start a new line in the text field, but I'm stufk on how to get there.
I've tried numerous fixes, but nothing gives the results I need.
I can send the entire file if It can help, but I don't want to post it all here.

You need to move the inserting of the header and footer fields into product loop eg. the custid and trx_id fields.
Here's a rough idea of one why you can go about this based on the pseudo code you provided. I'm sure that there are more elegant ways that you could code this.
set order = 0;
loop over cust_id;
counter = 1;
order = order + 1;
loop over product_id
if (counter == 1 || counter == 6) {
if (counter == 6) {
counter == 1;
order= order+1;
}
field[order][1] = "field(1)"; // cust_id
field[order][2] = "field(2)"; // name
field[order][3] = "field(3)"; // phone
}
field[order][counter+3] = productCode; // product_1
field[order][counter+4] = quantity; // quantity_1
counter = counter + 1;
if (counter == 6) {
field[order][14] = "field(4)"; // trx_id
field[order][15] = "field(5)"; // total_cost
}
end inner loop;
if (counter == 6) {
// loop here to insert blank columns and the totals field to fill out the row.
}
end outer loop;
One thing goes concern me. If you start a new line every five products then your transaction id and total cost is going to be entered into the file more than once. You know the receiving system. It may be a non-issue.
Hope this helps

As you put the data into the row, you need check if there are more than 5 products and then create an additional line.
loop over product_id
if (counter mod 10 == 0 and counter > 0) {
// create the new row, and mark it as a continuation of the previous order
counter = 0;
order = order + 1;
field[order][1] = "";
...
field[order][15] = "";
}
field[order[4+counter] = productCode;
field[order[5+counter] = quantity;
counter = counter + 2;
end inner loop;
I've actually done the export from an ecommerce system to MOM, but that code has since been lost. I have samples of code in classic ASP.
