It seems it dont work.
I placed debugs in the program just before and after and it crash in this command.
I am using 9.040
Bump!
Have you got a small bit of test code ?
Do you need any sample code because SPR2MEM does work on Gernot's palm?
If you could supply a small one, it would be handy.
Ok, here is an example that uses SPRITE2MEM
// A Tree image
image$ = "" _
+ "....****...." _
+ "..**++++**.." _
+ ".*++++++++*." _
+ "*++++++++++*" _
+ "*++++++*+++*" _
+ "*++++++*+++*" _
+ "*+++++*++++*" _
+ ".*++*+++++*." _
+ "..********.." _
+ "....####...." _
+ "....####...." _
+ "...######..." _
+ ""
DIM colors$[4]
colors$[0] = "."+INTEGER(0x00000000) // transparent
colors$[1] = "+"+INTEGER(0xff00ff80) // green
colors$[2] = "*"+INTEGER(0xff008000) // dark green
colors$[3] = "#"+INTEGER(0xff0080ff) // orange
MakeImage(0, 12, image$, colors$[])
LOCAL pixl%[]
SPRITE2MEM(pixl%[], 0) // get the sprite
LOCAL w%, h%
GETSPRITESIZE 0, w,h
MEM2SPRITE(pixl[], 1, w,h) // make a copy to see if it worked

This code has not been tested on Palm, as I am not at home, where my Palm is living.
It does look like its not working in as much as I just get a black screen...
Which could mean that MEM2SPRITE isn't working too...
Well, it is the sample code in the GLB manual about MEM2SPRITE command.
In my Win machine is shows 2 trees on screen.
Not tested on Palm. My game in Palm just closes as soon as it reach the SPRITE2MEM command.
Hmmm - what webOS version are you using ?
I just get a black screen...
2.1.0
This code has not been (yet) tested on my Palm. On Win, it shows 2 trees.
Tonite I will check it on my palm pre 2.
Anyway, it is shows a black screen (your) or crashes (mine), it is not working :D
I have just tested the MEM2SPRITE example on my palm pre 2. It crashed. No black screen or anything. Just a open&close of the screen.
oh bad. Does the console bring some output? (compiler/platform/webos/tools/bin/deviceShell)
Yes, crashes in glReadPixels. :/
