Compression and abbreviation for fixed length messaging

A method, computer program product, and data processing system for compressing and abbreviating text messages at a first text messaging device for transport and subsequent interpretation at a second text messaging device is disclosed. A user-defined message length reduction profile for producing human-readable compressed text is associated with a source text message at a first text messaging device. The source text message is then shortened using abbreviations and transformation rules in the profile. The shortened text message can then be transmitted to a second text messaging device. In addition, the compression provided by the present invention, although intended to be human-readable, can be complemented with decompression software to expand the compressed and abbreviated text to its full length and verifying, using a checksum or other error detecting code, that the expanded version corresponds to the original text.
