Intrinsic Data Types (Cont.)

Some examples of data type usage are given below:

.ascii .byte 
     .data 
 s:  .ascii  "xyz"
     .byte   0

     .text 
     la  $a0, s 
     li  $v0, 4
     syscall
 
     .data
 s:  .byte  'x'
     .byte  'y'
     .byte  'z'
     .byte  0

     .text
     la  $a0, s
     li  $v0, 4
     syscall
 
     .data
 s:  .byte 'x','y','z', 0

     .text
     la  $a0, s
     li  $v0, 4
     syscall
Output Output Output










The directives .half and .word automatically align their data and preceding labels to a halfword and word boundary, respectively.

Halfword Alignment .space Word Alignment 
     .data 
 X:  .byte  1
 Y:  .half  2

     .text 
     lb  $a0, X+1 
     li  $v0, 1
     syscall
 
     .data
 s:  .space   32

     .text 
      # Using $t0
      # Using $t0
     lw  $a0, s 
     li  $v0, 1
     syscall
  
 
     .data
 X:  .byte  1, 0
 Y:  .word  2

     .text 
     lw  $a0, X+1 
     li  $v0, 1
     syscall
