This is part 2 in my series of blog posts on RTI RID configuration tips. Each of these tips, unless otherwise noted, works in HLA 1.3, HLA 1516-2000, or HLA Evolved. Take a look at part 1 here, and stay tuned for future posts in this series.
RID files are written in Lisp
The RID file is written in MTL. MTL stands for MÄK Technologies Lisp. MTL is basically a limited form of the Lisp programming language. The primary purpose of the RID MTL file is to set specific variables which are parsed by the RTI’s MTL parser and loaded into configuration settings. The same goal could be achieved using other formats such as XML (another popular MÄK configuration file format), but there are advantages to MTL.
