Hi, sorry if this is just my ignorance but can I have access to values set by "set"? I know how to access current workdir value: it's just @workdir (as string), but can I retrive value of omp_num_threads (as integer or string, does not matter actually)? Or can I do something like "eval set omp_num_threads" [of course not in the current sence of eval] to get string "omp_num_threads: positive integer, currently 4" which I could parse next?
