  I know exactly how you feel. I wanted to do this quite a while ago and
spent several hours searching online for a solution. The only thing I came
up was to store each new number in the '.data' section of the program, like
so:

 section '.data' data readable writeable

 numberone  dt ?
 numbertwo  dt ?
 TempNumber1 dt 125.236

 section '.code' code readable executable

  FINIT
  FLD tword[TempNumber1]
  FSTP tword[numberone]

 Alternatively, you can probably make a macro that does this automatically
(I've seen some macros for MASM that do such a thing).

  That's about the extent of my knowledge; perhaps somebody else can prove
me wrong and tell you a better way (which would be nice).

Sincerely,
Brian Becker
