Re: How to scan an entire array all at once -- RPG400-L

Hi Steve, yes I know that arrays are not the best choice but the client does not have the Toolkit (and we cannot load software on the AS400 because the box is based elsewhere - and controlled by a third party vendor).

Maybe once they find out how poor the performance will be for this utility program they will buy it :-)

thanks for the help

Marilyn,

IMO, using an array is the wrong approach to solve this problem.
XML documents are not well-suited for handling in an array,
other than an array that in your case would be 1 x 2097152,
so that you could process it one byte at at time in order to parse
it - and I don't think you want to process it this way either!
You need use an XML parser to parse the data in order to
retrieve this information from the XML document.
If still available for V5R1,
you need the XML Toolkit for iSeries (5733-XT1):
