Change next order number

[stonda]

I would like to change the order number. I use a script in orderscript.pl to create the order number on this way : INTxxxxx. The script is :
$::s_sOrderNumber = "INT" . substr($$::g_pSetupBlob{CGI_ID}, -1) . substr("0000" . $nCounter, -4);
The last order number is INT12409 and I would like the next one to be INT12500.
Must I modify the order.num file or the orderscript.pl ?

You don't need to touch order.num.
Look in Help|Troubleshooting - half way down - order number.
You can change the next order number form there.
