7 * chkdef.cmd - checks that a .def file has no conflicts and is properly
\r
10 * returns nonzero if two symbols have the same code or a line has a wrong
\r
13 * returns 0 otherwise
\r
15 * the standard output shows conflicts.
\r
19 def_file = translate(def_file,'\','/')
\r
24 * `cmp' is zero when the file is valid
\r
25 * `codes' associates a name to a code
\r
26 * `names' associates a code to a name
\r
33 * This sed expression cleans empty lines, comments and special .DEF
\r
34 * commands, such as LIBRARY..., EXPORTS..., etc

\r
39 * First we find all public symbols from the original DLL. All this
\r
40 * information is pushed into a REXX private list with the RXQUEUE

\r
48 * We retrieve the symbol name (NEW_NAME) and its code (NEW_CODE)
