You can see what these settings are and how they are set by running:
proc options option=pagesize value; run;
proc options option=linesize value; run;
Enterprise Guide lets you set this in it's options menu under Results -> General.
Enterprise Guide uses a Workspace Server (e.g. <SASConfig>/Lev1/SASApp/WorkspaceServer/WorkspaceServer.sh), so you could add a -pagesize option to the sasv9_usermods.cfg file in the Workspace Server directory.
Process Manager runs jobs using the Batch Server (e.g. <SASConfig>/Lev1/SASApp/BatchServer/sasbatch.sh), so you could add a -pagesize option to the sasv9_usermods.cfg file in the BatchServer directory.
