\par }\pard\plain \qj\widctlpar\adjustright \fs20 {SNM files should be placed in the \\system\\charconv directory of any drive. This will allow CharConv to find them.

\par 

\par If there are multiple SNM files, the effect is the same as having one SNM file made out of all the original source files concatenated and converted as one. In other words, the rules that CharConv uses are the union of all the rules in all the SNM files.

\par 

\par Only BASIC.TXT in the CharConv/data/SNM directory is built by CharConv\rquote s makefiles. One way to get another SNM file built automatically would be to update BASIC_SNM.MK in the CharConv/group directory.

\par }\pard\plain \qj\widctlpar\adjustright \fs20 {SNM files are binary files generated by SNMTOOL from a text file called the }{\b source file}{.

\par 

\par SNMTOOL is called from the command-line as follows:

\par 

\par }{\b\f2 SNMTOOL }{\i\f2 <source-file> <output-binary-file>

\par }\pard\plain \s2\sb240\sa60\keepn\widctlpar\outlinelevel1\adjustright \b\i\f1 {Testing SNM files

\par }\pard\plain \qj\widctlpar\adjustright \fs20 {Code to test the generated SNM file can be based on some of CHARCONV\rquote s own test code, e.g. \\charconv\\test\\source\\main\\TBIG5.*.

\par }\pard\plain \s2\qj\sb240\sa60\keepn\widctlpar\outlinelevel1\adjustright \b\i\f1 {The format of the source file

\par }\pard\plain \qj\widctlpar\adjustright \fs20 {This text files is case insensitive and permits comments beginning with a \ldblquote #\rdblquote 

 character and extending to the end of the line. It also permits blank lines and leading and trailing white-space on non-blank lines.

\par 

\par The source file consists of zero, one or more }{\b blocks}{ where each block contains the necessary information about a particular character set. The first line of each block is as follows:

\par 

\par }{\b\f2 CharacterSet}{\f2  }{\b\f2 0x}{\i\f2 <UID-in-hexadecimal>}{\f2 

\par }{

\par The remainder of the block consists of zero, one or more lines, each of which is either in the format

\par 

\par }{\b\f2 StandardName }{\f2 "}{\i\f2 <standard-name>}{\f2 "}{\b\f2 

\par }{

\par or in the format

\par 

\par }{\b\f2 MibEnum }{\i\f2 <MIB-enum-in-decimal>

\par }{

\par There may be more than one MibEnum and more than one StandardName line in the file. All of the enums and names thus specified are considered equivalent.
