An inline exit routine is considered to be an extension of the part of the application program (either mainline or asynchronous exit routine) that is executing when the inline exit routine is invoked. Effectively, an inline exit routine is entered through a branch from an RPL-based or CHECK macroinstruction just before that macroinstruction returns to the next sequential instruction in the application program.

After it completes processing, an inline exit routine can return to VTAM®. If it is coded to return to VTAM, the application program receives control at the next sequential instruction immediately after the RPL-based or CHECK macroinstruction that caused the inline exit routine to be invoked. If the inline exit routine is coded not to return, the application program branches to another location after issuing the RPL-based or CHECK macroinstruction.
