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