- ?X: This unit produces a shell script called Cppsym, which can be used to
- ?X: determine whether any in a list of symbols is defined by the C compilation
- ?X: chain (C preprocessor symbols plus C compiler native ones).
- ?X: It can determine the status of any symbol, though the symbols in $al
- ?X: are more easily determined. If you want to add to $al you can do
- ?X: it in Myinit.U.
