As I said, IBM is inconsistent with its terminology. The TSO/E REXX Users Guide, and the corresponding REXX Reference, define and use the term "Host Command Environment". But the control blocks refer to "subcommands", which is probably a legacy from REXX's CMS roots, and as you say, MFC uses "external environment".
