-+ (plus sign) (C++ only)

In z/OS® XL C/C++, you could use the -+ option to compile any source file as a C++ language file. The -x c++ option, which is supported by Open XL C/C++ for z/OS, has an equivalent function that treats all files as C++ source files regardless of their file suffixes. Note the following differences between -x c++ and -+:

• The -+ option is not sensitive to position on the command line. You can specify the input files and the -+ option in any order on the command line. However, the -x c++ option affects only the files that are specified following the option on the command line, but not those that precede the option.
• The -+ option treats all source files as C++ except files that have the .a, .o, .so, .S, or .s suffixes. However, the -x option accepts all these file suffixes. For example, if you specify the a.o file after -x c++ on the command line, the compiler treats a.o as a c++ file, which might result in errors.
