I wasn't sure it was QEMM (that's why I said 'or something'.  It DOES
require either Lahey Ergo OS/386 ($395) or the Ergo Developer's Kit
($695).

This is correct, at least as far as the code size.  Sorry for my mistake.
Obviously, by '64K of data' you don't mean the size of external data
files, which your program couldn't care less about. Data read into arrays
will increase the size of your compiled code, so in that sense the 64K
is a limit.  In addition there is a 64K limit on stack size and saved
local variables in Lahey Personal Fortran.
