Hallo Antonio,
so, basically the error is that it cannot handle escape characters, e.g. \".
Here are some tests:
Syntax error on 7613:20 token recognition error at: '" <?xml version=\"'
Syntax error on 3743:20 token recognition error at: '"upd_cmd desc: \"'
Syntax error on 523:3 token recognition error at: '"Error opening file.
PATH: \"'
sprintf (trace_msg,
"Error opening file. PATH: \"%s\" FILE: \"%s\"",
getenv ((char *) PATH), afilename);
Syntax error on 628:37 token recognition error at: '"Cannot get total
number of bytes from message \"'
snprintf(errMsg, MY_ERR_LEN, "Cannot get total number of bytes from
message \"%s\"", sizBuf);
Syntax error on 856:8 token recognition error at: '"<dto-ref ID = \"'
Syntax error on 80:22 token recognition error at: '"Object 1:
Name: \"'
str[0] = (char *) "Object 1: Name: \"OS\"\n";
Syntax error on 29:9 token recognition error at: '"HTML <h3><li><a name=\"'
Syntax error on 388:6 token recognition error at: '"%s DATA
user_id = \"'
Syntax error on 180:12 token recognition error at: '"first line = \"'
Syntax error on 155:8 token recognition error at: '"#include \"'
fputs("#include \"common_types.h\"\n", errorMsg);
Syntax error on 245:3 token recognition error at: '"Host list: \"'
Syntax error on 499:11 token recognition error at: '"\CreateUser (\"'
Syntax error on 67:9 token recognition error at: '"uptime |awk '{print \"'
Syntax error on 51:14 token recognition error at: '"s=\"'
Syntax error on 41:55 token recognition error at: '"00\"'
Syntax error on 3040:4 token recognition error at: '" \"'
Kind regards,
John.
