    Here is my program code for generation of fibonacci series from 1 to 100:-

    MVI C,01H
    LXI H,2100H
    MOV M,C
    MOV B,C
    MOV A,C
    LOOP: ADD B
    CPI 01H
    JC L1
    CPI 64H
    JNC L2
    INX H
    MOV M,A
    L1: MOV B,C
    MOV C,A
    JMP LOOP
    L2: HLT

    OUTPUT:

    2100->01
    2101->01
    2102->02
    2103->03
    2104->05
    2105->08
    2106->0D
    2107->15
