mov ax,WORD PTR [FSIZE]
add ax,OFFSET ENDPROG - OFFSET PROG

Hi im trying to learn assembly.
Above lines are intended to assembled with TASM. but im using NASM and when i assemble them with nasm, i get errors for lines with OFFSET, WORD PTR and BYTE PTR. How can fix the code to assemble it with nasm. (when i just delete above statements (eg. mov dx, FNAME) thoes errors dont show up, but is it right to do that?)
thanx.
