I'm trying to define some ten-byte x87 values in hex and fasm seems to not support this. I have to work around like follows:

Code:

myValue: dq 0x97ba1234436a63f6
         dw 0x7fdc

         fld tbyte [myValue]

instead of much simpler (would-be syntax)

Code:

myValue dt 0x7fdc97ba1234436a63f6

        fld [myValue]

Could support for this be implemented in fasm?

Manual wrote:

...and dt accepts the word and quad word value separated with colon, the quad word is stored first. The dt directive with single expression as parameter accepts only floating point values and creates data in FPU double extended precision format.

Code:

dt 0x7fdc : 0x97ba1234436a63f6

That should do it.
