Here's the output of "size," which doesn't tell me much....I think. Unless in v7 data has to be under 32K rather than 64K? Surely not, right? (The data segment is 32K of main memory for FORTH, plus some for the startup Forth script, plus a bit for the line buffer and some miscellaneous pointer variables.)

$ size forth.o

7580+34034+0 = 41614b = 0121216b

I think we also sometimes forget how small 64K was. Terseness wasn't
a choice.
