It worked fine on a single input file, but I wanted to read mulitple files and parse them in the same way. The program always aborted from the parser on the second file saying that EOF had been reached. I tried setting yyin to a new file pointer before calling yyparse but it did not help. Eventually I changed the skeleton file to remove the 'static' definitions from the function 'yyrestart'. Now from the routine which calls yyparse, I set yyin to stdin (so yyrestart won't try to close some other file), then call yyrestart with a pointer to the file I want to read. This has the desired effect, but now the line number counting I have put in the .l file is off by the number of lines in the previous file. Is there a correct way to read multiple input files with one parser run? -- Andrew Thomas andrewt@watsnew.waterloo.edu Systems Design Eng.
