    hello i need a program in assembly( tasm)

    Use the lower 4 bits of the pc parallel data port and connect it to the seven segment display inputs. The input A is the least significant bit, and input D is the most significant bit. Use the upper 4 bits of the data port and connect to the socket for the second seven segment display.

    Make a two digit up counter using two 7-segment displays

    what would be the logic for up counter from 00 to 99 as i am using a BCD decoder

    The programming is up to you. Here is a link to how to use the printer prot that should answer all your questions - http://www.beyondlogic.org/ecp/ecp.htm.

    You absolutely must understand the hardware before writing code.
