 the cleanup code at every exit spot. Multiple defers can be scheduled in a single subroutine (up to a maximum of 8).

     A Prog8 library module that provides Commander X16 style RAM banking on a C64 with an REU.
     This module provides cx16.rambank(), x16jsrfar() and extsub @bank functionality on a C64.

+    An example of a simple utility that can link symbols in a main Prog8 program

+    It pre-processes the debug symbols list file at compile time,
+    and substitutes references in a template module file.

+    but also in the main program and copied into the library for its use.
