PDP11GUI MACRO-11 Code window
This a special Memory window. It shows the code which was extracted from a MACRO-11 Listing.
An assembler file translates not necessarily into one single continuous code block. In the example, the program contains trap vectors at low addresses, and two code segments at two different start adresses. Hence there are many undefined memory addresses between the code data.
You can change the code, and Deposit the result. The addresses are 18 bit or 22 bit physical addresses.All memory values are assumed to be new, so they are higlighted until deposited.
