SET DEVICE
SET DEVICE PRINT | SCREENSelects output destination in historical eAdvPL.
Overview
Historical eAdvPL reference, section 1.3. Syntax depends on that implementation’s macros and platform; current SmartClient support is unconfirmed. The guide records PRINT and SCREEN. Other AdvPL dialects use SET DEVICE TO PRINTER; check includes before mixing variants. Destination selection does not configure drivers, document opening, pagination or spool. This subset only returns to screen; it neither implements printing nor closes caller-owned resources. (Sources: refs. 1–1.)

Requests screen output in the documented variant. Under review: editorial example neither compiled nor run in Protheus. Check includes, release, RDD and context before testing.
- Verify includes and graphical context in the target release. The fragment assumes the stated objects; it is not a complete application. Do not use in headless execution.
