how are you looking at the pgm memory , I think something is not right

for me the da and data directives produce exactly the same result , I left the da directive in, thinking I might try the code on a pic16f1825 for a learning experience , for 7 bit ascii data either will do (pic 18's can store 2x8 bit ,pic 16's 2x7bit )

the relevant listings
Code:
0
0013E 6854 7369 6920 00199  data "This is a string",0
          2073 2061 7473 
          6972 676E 0000
Code:
00013E 6854 7369 6920 00199  da "This is a string",0
