Download the attached file and copy it into the same directory that you save the code below into. Its an over engineered example to achieve a "box" on the screen but hopefully you can pick a few other things up that you are going to need.
Personally I think you might need to start smaller but I wish you all the best and hope you succeed.
SET DISPLAY MODE 640,320,16
LOAD IMAGE "box.tga",1
dim RPGText$(6)
for r=1 to 6
read rpgtext$(r)
NEXT r
txtptr=1
while txtptr<6
PASTE IMAGE 1,25,70
text 105,80,rpgtext$(txtptr)
text 105,100,rpgtext$(txtptr+1)
text 105,120,rpgtext$(txtptr+2)
text 260,160,"Press any key"
WAIT KEY
txtptr=txtptr+3
endwhile
