Frequently Asked Questions
What OPX libraries are supported?
OPX libraries are native C/C++ libraries that OPL programs can use. The following built-in and commonly used OPX libraries are supported:
- bmp.opx – fully supported
- date.opx – a few unimplemented functions
- sysram1.opx – common functions supported
- system.opx – common functions supported
- systinfo.opx – partial support
