True. But there is another issue attached to the one i wrote.
When i know how much this occurs, i know the amount of pages in the
file. After that i would like to be able to extract a given amount of
data:
file x contains 20 <0C>. then for example i would like to extract from
instance 5 to instance 12 from the file.
The reason why i want to do this: The 0C stands for a pagebreak in PCL
language. This way i would be absle to extract a certain amount of
pages from the file.
