Explanation
TYPE=SCAN is a JCL parameter that validates the JCL syntax for errors without executing the job. It's a syntax-checking feature, not related to previous jobs or doing nothing.
AI explanation
TYPRUN=SCAN (or TYPE=SCAN) on a JOB card tells the system to scan the JCL for syntax errors without actually executing any of the job steps. It's a dry-run/validation mode used to catch JCL problems before committing resources to a real run.
