Size of Extrn Variable Does Not Generate a Constant

Problem:

The size of extrn variable does not generate a constant. MASM marks

size operators on extrn symbols as external; during load, the

immediate value is relocated.

In the following example, during run time, CX contains 4 plus the base

address of sym:

extrn sym:dword

CODE SEGMENT BYTE PUBLIC 'CODE'

mov cx,4 ; marked correct

mov cx,size sym ; marked external

CODE ENDS

end

Response:

Microsoft has confirmed this to be a problem in Version 4.00 of the

Macro Assembler. This problem was corrected in Version 5.00.
