PROC GREPLAY will hang when the IGOUT= and GOUT= options on the PROC GREPLAY statement point to different catalogs. This problem only occurs when multiple graphs are created with a single SAS/GRAPH procedure (for example, when using a BY statement). Once the SAS session hangs, the only option is to terminate the SAS session using Windows Task Manager.

To circumvent the problem, make sure that the IGOUT= and GOUT= options on the PROC GREPLAY statement point to the same catalog. Since the default catalog for the GOUT= option is WORK.GSEG, the following PROC GREPLAY statement will hang the SAS session:

proc greplay igout=gc1 nofs tc=sashelp.templt 
             template=l2r2;

To correct the problem, add the GOUT= option to the PROC GREPLAY statement, making sure that the GOUT= option points to the same catalog as the IGOUT= option. Here is an example:

proc greplay igout=gc1 gout=gc1 nofs tc=sashelp.templt 
             template=l2r2;
