Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     The tiny memory model allows you to create a program with the .COM
     extension. Tiny-model programs execute only under DOS, are limited
     to 16-bit segments, and cannot have relocatable addresses. You can
     invoke the assembler with the /AT option to use this memory model.
     This tells the assembler to check for relocatable addresses. The
     /AT option also passes the /T option to the linker.
 
     With the tiny-model option, code and data segments are combined
     into a single 64K segment. Both code and data items are accessed
     with NEAR addresses. The PROC distance is NEAR under the tiny-
     model option. @CodeSize is 0, @DataSize is 0, and @Model is 1.
 
     The .STARTUP directive automatically generates an ORG 0100h under
     the tiny-model option. The .FARDATA and .FARDATA? directives are
     not allowed with the tiny-model option. The FARSTACK option of
     the .MODEL directive is also not allowed.
