When using the PDF wrapper (not the Java Transformers) a PDF page is being split after 60 lines.
Spool PDF wrapper
This file was created with LINECNT=60 so it will always break the page after 60 lines.
The application has to be changed to allow more lines per page or set LINECNT=0
Alternatively, the following DESTID statement can be used to force a specific line count:
DESTID QDEST=prt,FLINECNT=66
DESTID QDEST=prt,FLINECNT=0
