Sure, here's an example MIPS assembly language program for shift logical left:
```
.data
input: .word 0x0000000F # 4-bit input value
.text
.globl main
main:
lw $a0, input # load input value into $a0
sll $a0, $a0, 2 # shift $a0 left by 2 bits (multiply by 4)
# output result
li $v0, 1 # set $v0 to print integer
move $a0, $a0 # move result into $a0 (for printing)
syscall # print result
# exit program
li $v0, 10 # set $v0 to exit
syscall # exit program
```
In this program, we start by defining a 4-bit input value in the `.data` section. Then, in the `.text` section, we load the input value into register `$a0` using the `lw` instruction.
Next, we use the `sll` instruction to shift `$a0` left by 2 bits (multiply by 4). The `sll` instruction takes three operands: the destination register (in this case, `$a0`), the source register (also `$a0`), and the number of bits to shift by (2 in this case).
After performing the shift, we output the result using the `li`, `move`, and `syscall` instructions. Finally, we exit the program using the `li`, `syscall` instructions.
