Using PRINT statements in Adaptive Server stored procedures – PB Docs 2022

The ASE or SYC Adaptive Server database interface allows you to use
PRINT statements in your stored procedures for debugging purposes.

This means, for example, that if you turn on Database Trace when
accessing the database through the ASE or SYC interface, PRINT messages
appear in the trace log but they do not return errors or cancel the rest
of the stored procedure.
