The CC8BITLEVEL environment variable
determines the type of processing that the filter, esqlmf,
performs on non-ASCII (8-bit and multibyte) characters.
The esqlmf filter converts all non-ASCII characters
in literal strings and comments to octal constants (for C compilers
that do not support these uses of non-ASCII characters).
1
The esqlmf filter converts non-ASCII characters
in literal strings to octal constants but allows them in comments
(some C compilers do support non-ASCII characters in comments).
2
The esqlmf filter allows non-ASCII characters
in literal strings and ensures that all the bytes in the non-ASCII
characters have the eighth bit set (for C compilers with this requirement).
3
The esqlmf filter does not filter non-ASCII
characters (for C compilers that support multibyte characters in literal
strings and in comments).
To start esqlmf each time that you process the source file with the esql
command, set the ESQLMF environment variable to 1. If you do
not set CC8BITLEVEL, the esql command assumes a default
value for CC8BITLEVEL of 0.
Important: When
ESQLMF is set to 1 to enable automatic multibyte filtering, do
not set CC8BITLEVEL to 3.
