Emulator/Analyzer Interface Commands
--EXPR--
Note that when a thru softkey has been entered, a <+ EXPR> prompt
appears. This saves you from tedious repeated entry of long symbols and
expressions. For example:
disp_buf thru +25
is the same as
disp_buf thru disp_buf + 25
Examples
05fxh
0ffffh
disp_buf + 5
symb_tbl + (offset / 2)
start
mod_name: line 15 end
