Thanks to all for the replies, it all makes sense, given that I cannot pull the stove out from the wall to check to see just what type wiring is there (too heavy) I can partially see the back of my dryer, however, and that appears to be the normal, super-thick looking thing-y cord for a standard, 220volt outlet. Have high hopes the stove will turn out to the be same (?)
Interestingly, the sales staff at the store (Sears Hometown outlet) was speculating on 3 prong vs 4 prong, hard-wired or not, issues as well. Mainly because Whirlpool stove I am replacing is circa 1979 model

, originally put in by the builder.
Yes, forty years

but real story is: I bought the house from a rather strange duck who never used either the stove or dishwasher for the 13 years of her ownership. So, the stove did not technically "last" for 40 years, but rather 26.
Which I consider to be pretty darn good for longevity.
