Which SAS function would help in identifying issues during macro execution?

The function that assists in identifying issues during macro execution is OPTIONS MLOGIC. When this option is enabled in a SAS session, it prompts the system to display messages in the log that describe the resolution of macro variables and the execution of macro statements. This information helps users to trace the flow of macro execution, making it easier to diagnose problems or unexpected behavior in their macro code.

In contrast, PROC CONTENTS is used to display the contents of a dataset, allowing users to understand its structure and attributes but does not provide insights into macro execution. PROC PRINT is designed to display the actual data in a dataset, offering a way to inspect data rather than debug macro behavior. PROC REPORT serves a similar purpose to PROC PRINT but is used for more customized reporting and does not contribute to macro debugging. Thus, enabling OPTIONS MLOGIC is specifically tailored to facilitate the debugging of macro issues, making it the appropriate choice for this context.
