I was cut off! Sorry about that. As I was saying...
One should not put a null character in a comment since the Unix
debuggers tend to stop printing when they encounter a null.
For example, when I examine strings while debugging, I have found
that the full string will not be printed if a null is embedded:
Example : Strin(1..7) ;
Example := "ABC" & Character'Val(000) & "DEF" ;
Examinging Example will result in:
Example = "ABC"
In addition, useful tools like Vax's CMS won't accept some control
characters inthe source code (at least the old versionI am using).
Therefore, my recommendation is to stick to the visible character
set including foreign characters which AI-00339 was actually aimed
at. Also, when debugging, examine strings in hex first to see if any
nulls are lurking about.
