DESCRIPTION This file has definition of types that are PL/SQL PUBLIC (i.e. used by RDBMS, ICD implementors etc.) and that are also common to the NATIVE and INTERPRETED execution environments. **!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! **!!!! THIS FILE IS SHIPPED FOR NCOMP. !!!! **!!!! !!!! **!!!! If you change it for a bug fix, you will need to make !!!! **!!!! sure it is re-shipped also along with the new binaries.!!!! **!!!! Please make this note in the BUGDB along with your fix.!!!! **!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! CAUTION: Do not put any interpreter specific definitions in pen.h (or files included by pen.h such as pvm.h/pdtyp.h/pptyp.h). Such definitions belong in pfrdef.h/pfmdef.h. Internal support functions not required by generated C code belongs to pet.h/pvm0.h.
