i don't know about those commands but heres an example of loading tiles
rem load image "grass.bmp",1
rem load image "water.bmp",2
rem make some 20*20 tiles to use
ink rgb(0,255,0),0
box 0,0,20,20
get image 1,0,0,20,20
cls
ink rgb(0,0,255),0
box 0,0,20,20
get image 2,0,0,20,20
cls
rem set spme variables
grass=1
water=2
imagesize=20
rem for next loops
for y=1 to 5
for x=1 to 5
rem read data at the bottom into variable 'a'
read a
rem acorrding to what a is paste the right image in the right place
if a=1 then paste image grass,x*imagesize,y*imagesize
if a=2 then paste image water,x*imagesize,y*imagesize
next x
next y
rem wait for keypress
wait key
rem load map 2 from data
for y=1 to 5
for x=1 to 5
rem read data at the bottom into variable 'a'
read a
rem acorrding to what a is paste the right image in the right place
if a=1 then paste image grass,x*imagesize,y*imagesize
if a=2 then paste image water,x*imagesize,y*imagesize
next x
next y
wait key
rem reset the data pointer back to map1 so we can load it again
restore map1
rem load map1 again using same code as above
for y=1 to 5
for x=1 to 5
rem read data at the bottom into variable 'a'
read a
rem acorrding to what a is paste the right image in the right place
if a=1 then paste image grass,x*imagesize,y*imagesize
if a=2 then paste image water,x*imagesize,y*imagesize
next x
next y
wait key
rem data
map1:
data 1,1,1,1,1
data 1,1,1,1,2
data 2,2,1,1,2
data 1,2,1,1,2
data 1,2,2,2,2
map2:
data 1,1,1,2,2
data 1,1,1,2,2
data 1,1,1,1,1
data 2,2,2,2,2
data 1,1,1,1,1
