Hi All,

Ok this one has me scratching my head, and my head is getting very red...

This simple test just saves a string into memory, then tries to pack that memory and unpack it, but fails to unpack.

Can anyone tell me what I am doing wrong here, Please...

Code: Select all

sText.s = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
nLen.l = Len(sText)

If nLen And AllocateMemory(0,nLen, 0) And AllocateMemory(1,nLen+8, 0)

  PokeS(UseMemory(0), sText)

; fails on next line
  nPackLen.l = PackMemory(UseMemory(0), UseMemory(1), nLen, 9)
  If nPackLen <> 0 

    AllocateMemory(2,nLen+8, 0)

    nUnPackLen.l = UnpackMemory(UseMemory(1), UseMemory(2))

    sNewText.s = PeekS(UseMemory(2),nUnPackLen)

    Debug "Result:" + sNewText

  Else
    Debug "Pack Mem Failed"
  EndIf
Else
  Debug "No Mem Allocated"
EndIf

Can anyone make this work, many Thanks

For me it fails to pack the memory, you should maybe use a longer string or a more repetetive string so you actually gain when trying to pack..
