This is probably going to bring back some memories (Hello, Anders, if you are reading this!)
The first two pages (855kB) give an idea of what this language involved. It became a popular language indeed!
Blue Label Pascal (also known as BLS Pascal - Blue Label Software) is interesting. Poly-data, a Danish company, produced this for the Nascom machines. It appears to have been written by Anders Hejlsberg. As from December 1981 distribution was taken over by Lucas Logic (and a few small changes made), who renamed it to Nascom Pascal and sold it in EPROM and cassette formats. Gemini produced a larger, more expensive disk-based CP/M version called COM-PAS or COMPAS depending on what you read. It just happened to have been written by the same person! It would appear that this version later formed the basis for Borland Turbo Pascal and its subsequent developments on the PC. According to a recent article in Personal Computer World Anders has also been involved with J++ for Microsoft.
