Out of memory!

[Edson Alvarenga (EDB)]

Hi everybody,

I'm writing a script file in order to get the print queues, but when I call the 
function EnumJobsA at the first time in order to know what is the size that I need to 
allocate for the buffer the function return the value 538976288 and when I try to 
allocate this value in a buffer variable the system abbend the script and return the 
error message "Out of memory!".

Any ideas?

Thanks a lot for your attention.
