Haven't read all the responses so this may be a duplicate.

Running your original code I just got back the values in the variables rather than their evaluated values.
So I tried
STORE EVALUATE(EVALUATE("m.HMF" + PADL(ALLTRIM(STR(nCounter)),2,"0"))) TO nValue
which gave a "Missing Expression" error

I then tried
m.KHour = 300

HMF01 = "m.KHour * 1100000 / 110 "
HMF02 = "110000"
HMF03 = ""

FOR ncounter = 1 TO 3
STORE EVALUATE(EVL(EVALUATE("m.HMF" + PADL(ALLTRIM(STR(nCounter)),2,"0")),'0')) TO nValue

? nValue
ENDFOR
and it seemed to work
