Hi,
Rather than "pause" ODS, I suggest taking a different approach:
[pre]
** 1st SAS/Graph pgm for chart (outside ODS "sandwich");
** 2nd SAS/Graph pgm for chart (outside ODS "sandwich");
ods pdf file='somefile.pdf';
proc greplay igout=work.gseg
tc=sashelp.templt template=v2s nofs;
treplay 1:gchart 2:gchart1;
run;
quit;
ods pdf close;
[/pre]
Basically, make sure that ONLY the GREPLAY step is inside the ODS "sandwich" for ODS PDF.
So you'd create all your graphs first in the work.gseg catalog and then do the greplay.
When replaying to PDF or sending graph output to PDF in general, you may find this Tech Support paper to be useful:
http://support.sas.com/techsup/technote/ts659/ts659.pdf
It discusses some techniques that you may find helpful including ODS-based approaches and GSFNAME approaches and ODS LAYOUT approaches.
Good luck,
cynthia
