EMC has feed hold (P for pause and S for resume) as well as number
keys for 10 to 100% feed rate override, plus a slide bar for 0 - 120%
feed rate with the mouse.

EMC has a cutter length and diameter list that is used when tool length
offset or cutter diameter offsets are in use.

Well, EMC doesn't have a separate macro language for tool path creation, but

there are user variables and the ability to say things like
G01 X[variable1001+1.2345] and the ability to increment or otherwise
alter the contents of the variables. this allows a program to be re-run

to perform the same operation in several different locations without
manual
entries. EMC does lack a looping capability, although some ingenious
workarounds have been made.

EMC does have a VERY powerful macro language associated with the
user interface, Tk/TCL. This allows the screen representation to be
easily altered without touching the internal code of EMC, and allows
some "conversational" G-code geberators to be attached to EMC
to write code for pocketing routines, thread milling, peck drilling
cycles,
bolt circles and grids of holes, etc.

This is a sore spot, and people are working on it so that EMC can do
all lathe functions.
