This is a post processor thing. The post needs to be set up to output code in the format you want and that is done by editing the GPP file. The first place to look is in the SolidCAM Settings menu and make sure that the default post processor (default CNC Controller in SolidCAM speak) is set to the right one. If you have just installed an upgrade you may have overwritten the old settings.
Do you have a backup copy of your old post processor.
