The correct forms of a significant subset of misspellings are not single words, but rather two or more words. To correct this problem for programs which assist an operator in making spelling corrections, the two or more correct words are represented as a single entry in the source dictionary with "virtual blank" characters separating the words. The virtual blank characters are transparent to the spelling assistance application, and can be stored and compacted as would any other character. In the decode phase, the virtual blank character is converted to an actual blank before being displayed. As an example of this technique the misspelling "allright" is not correctable under the prior-art technique. With the present improvement the correct form "all right" is presented as a candidate by the spelling assistance program.
