If your checkpoint-restart library is a user-defined library, you must add the LIBNAME statement that defines the checkpoint-restart libref as the first statement in the batch program. If you use the WORK library as your checkpoint library, no LIBNAME statement is necessary.

The checkpoint-restart data contains only information about the DATA and PROC steps that completed and the step that did not complete. When these options are in effect, SAS acts as follows: reads the remaining statements in the DATA step or PROC step checks that statements are valid SAS statements executes global statements I check for an error code (&SYSERR or &SQLRC). asked 4 years ago viewed 10950 times active 10 months ago Get the weekly newsletter!
