1.main differerance between and a high level language and a low level language is hardware dependece. as you are firm to use 51 instruction set assembly will be best.

2. if HLL is used no hardware know how is required. when using 'c' for 51 you have to learn about the hardware even HLL is used.

3. as you have lil know how of 'c' and have to start from the zero, better to start learn assembly. abstarction of 'c' may cause confusions.

4. my approach, when i program a PC in assembly , i write only those portions in assemblr where i doubt 'c' compiler can generate code lesser in size and faster than assembly. here i donno' 51 'c' compilers support _asm{} statment.

note: i'm a big assembly supporter because i learned the assembly first and even though have to write long and bulky code.i dont think its hard to learn as far as 8051 is cocerned. PC programming 'c' is vastly used. because there is an platform is also involved what we call operating system. but here , its a differant case.

phew!
