I'm allocating a blob to use for the output from a Windows API function:

lblb_Buffer = Blob(Space(lul_BufferSize), EncodingAnsi!)

Buffer size is 262,164,339.

The result is:

---------------------------
PowerBuilder application execution error (R0108)
---------------------------
Application terminated.

Error: Not enough memory to execute the operation at line 28 in function compress of object n_compression.
---------------------------
OK
---------------------------

 

This is a demo app just for the Windows API functions so nothing else is going on in the app.

Customer stated that the built-in CompressorObject/ExtractorObject are too slow so I put together an example of the Windows functions Compress/Decompress. They are fast but the above problem limits use.

Is there some other way to allocate a blob? This is a little under 256 MB which isn't that large when dealing with files.
