let say if im using like

LD 0.00
T 0000
out 100.00

can it be like this?

Function (88) - 7SEG.

Your answer is no, it will not work. Follow what Bob said and than wire it correctly. You will need more than one output bit to drive the display.

Here is a Truth Table for one Digit of a 7 Segment Display.

If you don't like this one, just do a Google search. You will need these Bits for each Digit you want to display.
