I used the software RCBasic several years ago. Being an amateur,  it is a very user-friendly language. The language is reliable and good. I read a detailed post written by its author today. It is a brief technical introduction to the software. The introduction is interesting and the RCBasic manual never talks about technical details of RCBasic.

In my view, RCBasic is a very nice software and I encourage BASIC hobbyists to download to try this free software..
