If you know address and type already, for what do you need scanmem then?
There is the dump command. Also ugtrain can watch a configured variable in memory before starting to modify it.

I'm not convinced this should be separate from the dump <addr> <len> command, but if we want it just to give a nice presentation of the read data we should refactor it and dump so that they share most of the code, not repeating it in both places.

@superprogram This is not the right place for such requests, this is for code discussion.
If you are a newbie, use gameconqueror, that has a user friendly interface.
