2.1 Character Set and Separators ¶
- The character set used should be plain 7-bit ASCII.
The only separators allowed are space and the end-of-line sequence.
No other control character or format effector (such as
HT,
VT, FF )
should be used.
The normal end-of-line sequence is used, which may be
LF, CR/LF or CR,
depending on the host system. An optional SUB
( 16#1A# ) may be present as the
last character in the file on hosts using that character as file terminator.
- Files that are checked in or distributed should be in host format.
- A line should never be longer than 79 characters, not counting the line
separator.
- Lines must not have trailing blanks.
- Indentation is 3 characters per level for
if statements, loops, and
case statements.

elements, see file style.adb.
