Seems likely given the BCPL implementation was based on a VM.
- Rochus 4y agoWas it really a VM, or wasn't just the O-code translated to microcode by the compiler?
- igouy 4y agoVM enough to be discussed in a book about Virtual Machines :-) https://www.google.com/books/edition/Virtual_Machines/vIB-npHEbd4C https://www.google.com/books/edition/Virtual_Machines/vIB-np...
- Rochus 4y agoThere was indeed an interpterer for O-code; but according to http://www.bitsavers.org/pdf/xerox/alto/bcpl/AltoBCPLdoc.pdf http://www.bitsavers.org/pdf/xerox/alto/bcpl/AltoBCPLdoc.pdf the Alto BCPL compiler generated relocatable binary files.
