I am interested in learning whether the 387 supports the extended addressing features of the 386. For instance, the sample instruction fld dword ptr [esi][eax*4] assembles fine both in MASM and TASM. But when executed, (yes, it seems to execute ok) the 387 does not load the correct data. (pc, real mode). If I 'mov' the data to a 386 register it shows up fine, so I know the address is properly formed. And if I convert the address to the conventional [si][bx] form, all is fine also. Incidentally, I'm using Borland TD to make these observations. Does anyone know about this? Thanks in advance for any help. -- Ray Berry kb7ht uucp: ...ole!ray CIS: 73407,3152 /* "inquire within" */ Seattle Silicon Corp. 3075 112th Ave NE. Bellevue WA 98004 (206) 828-4422

Call off the hounds. TASM gets the award for this one. Although
the list files show that tasm and masm both emit the same code for this
instruction, the instruction fails when the tasm module is linked but
works fine when the masm-assembled module is linked. The tasm vers I
have is the original 1.0, and not what is currently shipping (1.01?).
