Syntax: SET LANGUAGE COMPILE COMMAND compile_command defined_language Specifies the default command string for the COMPILE command. This string is the command used to compile a buffer when the COMPILE command is used. If the language has diagnostic capability, and you want a diagnostics file created for use with the REVIEW command, you must specify the diagnostics switch in the command. For example, on OpenVMS systems: SET LANGUAGE COMPILE COMMAND "CC/DIA"
