Compressed data is binary - so you can't display it in a field. That
explains the strange behaviour you have been seeing. You need to convert it
to text if you want to copy, display or save it as text. To do that, use
the base64encode function (then use base64decode and decompress to access
the data again). If you're using the Starter Kit, you can also shorten this
to just one line for compress/encode and one for decompress/decode like
this:
put base64Encode(compress(the text of fld "whatever")) into tCompressedData
put decompress(base64decode(tCompressedData))
