TXTALIAS is a true ZCPR3 tool that "compiles" standlone aliases 
from standard ASCII "source" files.  Conceptually similar to 
ACREATE and BA24, but supports assembler-style comments and 
multiple newlines in the source file, has Joe Wright's latest 
ALIAS0 built-in rather than using a separate "alias template" 
file, allows VALIAS-style "recursive" aliases, and has Program 
Error Flag support for automation of alias "development."
