These functions manipulate the data content of the current blob area.
If the field filtered by these functions has a zero
length, the filter function returns zero (0). Transaction production
treats this return as a failure. To allow a zero length on the field,
do one of the following:
Use a rule-level error function to trap this condition and force a continuation of processing.
Use rule-level qualification to skip the whole transaction.
Provide a default value in the related field object.
Removes white space (blanks) between a comma and any value that follows it. Use this filter function to shrink words into a single, unified whole.
None.
Converts alphabetic characters in the current blob area to lower case. Returns the number of characters filtered.
None.
Converts alphabetic characters in the current blob area to upper case. Returns the number of characters filtered.
None.
Starts from the blob area’s right-most position and removes trailing spaces and/or form manipulation control characters until it finds a specific character, as identified by the argument, or finds another character. If it finds the character in the argument, it also removes that character from the blob area. Form manipulation control characters include FF, LF, CR, VT, HT, and TAB. The function then adjusts its internal data about the current blob area’s length to the new value.
A character that delimits the trailing spaces deletion.
Capitalizes the first letter of every word in the current data field. Words are data elements in the current data field that are delimited by spaces, tabs, or backspace characters.
None.
