I am using tasm and using the assembler in dos ( real mode ). I am
quite confused with the .model directive. why exactly is the .model
tiny or large etc are used? Also if there are multiple data segments
greater than 64 kb can i use these simplified directives or should i
use the full segement definitions.Do i need to write the .model
statement even when i am using the full segment definitions? I am
particularly concerned with the data which is more than 64kb. Please
give me code example to explain so that it will be easier for me to
understand.

Thank you
