# Auxiliary ROMS Programs: - **`types.F`**: It checks the precision and range of floating-point variables in a particular compiler architecture. To compile and link, use: ``` ifort -o types.x types.F gfortran -o types.x types.F ``` - **`yaml_parser_test.F`**: It tests the **yaml_parser.F** available in **ROMS**. It requires the Fortran 2003 standard and a few features of the Fortran 2008 release, which are available in modern compilers. We have reports from users having issues compiling with older versions of **gfortran**. To compile and link, use: ``` ifort -o yaml_parser_test.x yaml_parser_test.F gfortran -o yaml_parser_test.x yaml_parser_test.F ``` It is easy to run by specifying the desired **YAML** files available in **ROMS**: ``` > yaml_parser_test.x Enter YAML filename: ../../ESM/coupling_esmf.yaml ... Enter YAML filename: ../../ESM/roms_cmeps.yaml ... Enter YAML filename: ../External/varinfo.yaml Enter YAML filename: ```
