TASM or Turbo assembler is the software which need to be used in BCSL-022 lab exam. No MASM or emu8086. In exam hall, systems will be equipped with TASM as it is comes along with Turbo C software.
Now you can run turbo assembler directly from any version of Windows Operating system without virtualization support like DOSbox. Complete software with IDE and TASM inbuilt is freely available for download from here
.So our lab book examples and lab exam system uses TASM only. So don;t use any other software as syntax difference will be there.
