Two types of errors can occur when you use SAS to process VSAM data sets. The types of errors are physical and logical. There are several things you need to know:
-
the differences between physical and logical errors
-
error detection
-
error-handling techniques
-
the FEEDBACK= variable and other error detection variables
-
VSAM feedback codes
-
how COBOL status key values correspond to VSAM feedback codes (see COBOL Status Key Values and VSAM Feedback Codes)
