Assembly syntax varable type PTR confusing

[lassar]

Doing fairly good with assembly, but this assembly PTR is drivng me crazy.

Getting a error on this statement.

Code: Select all

      MOV     UBYTE PTR [X%], 9

Can never figure out where to put UBYTE PTR: before the comma, after the comma or
before the [X%], or After [X%], before the 9 or after the 9.

Where do I put UBYTE PTR ? ? ?

Could someone help me with my confusion on this?

[SARG]

Is UBYTE allowed ?
Changed by BYTE it works...

[lassar]

Yes "Byte" does work, but since I have had so much trouble with this in the past,
would someone explain the assembly syntax of this.

Where do you put "variable type" PTR in a assembly statement?
