The -ttwrdrul parameter is a client startup parameter that is used to apply a word rule to a temp table within a Progress session. In Progress versions before 9.1A, a word break rule could be created, compiled and then applied to a database with PROUTIL, but the rule could not be used with word indexes defined within a temp table. For example, after creating and compiling the word break table into proword.14 and applying it to a Danish Version 9.1A Sports database, subsequent execution of the code below fails with the error "QBW syntax error - an asterisk (*) is allowed only at the end of a word. (4686)":
DEFINE NEW SHARED TEMP-TABLE tt_vare NO-UNDO
FIELD tekst LIKE customer.name
INDEX tekst IS WORD-INDEX tekst.
CREATE tt_vare.
ASSIGN tt_vare.tekst = "svend tågehorn".
FOR EACH tt_vare WHERE tt_vare.tekst CONTAINS "tå*":
DISPLAY tt_vare.tekst.
END.
However, if the session is started with:
prowin32.exe -cpcoll Danish -ttwrdrul 14
Then the code correctly returns the single tt_vare record.
It is important to remember that the proword.14 file must exist in the DLC directory, or the PROWD<nnn> environment variable must be set allowing Progress to find the word rule.
