MemEdit presents you with a view into CMM2's (virtual) memory and allows you to make changes. Essentially, it's a peek/poke front-end. The memory contents are shown as hexadecimal byte values and as ASCII code in two side-by-side blocks. Changes can be made both in the hex table section and in the ASCII section. The usual file navigation with cursors keys, page up&down, home, end, etc. should work as expected. MemEdit is a full-screen console-only editor. I does not work over serial, sorry. The starting address to view can be passed in as a command line argument, e.g. *memedit MM.INFO(PROGRAM) Commands such as goto and fill accept MMBasic syntax for address specifications, e.g. Go To Address (MMBasic syntax): MM.INFO(PAGE ADDRESS 0) Press F1 to get help on key bindings.
