Truncating Undefined Portions of Strings

You can define the properties for a string such that the Transaction Integrator (TI) run-time environment truncates undefined characters when it converts UNICODE strings to mainframe data representations instead of generating an error message. To do so, click Truncate under Error handling on the string's Host Definition tab (property page) in TI Project.

When truncation is turned on, the TI run-time environment limits the number of characters to the string's previously specified dimension value when it converts a character string to an Extended Binary Coded Decimal Interchange Code (EBCDIC) or double-byte character set (DBCS) character string.

When it converts to intermixed strings, the TI run-time environment ensures that all shift-out (SO) characters have matching shift-in (SI) characters. It adds a terminating SI character when truncation occurs in the middle of a contiguous stream of DBCS characters. Also, the TI run-time environment ensures that it does not leave a partial DBCS character when it adds the SI character.

If blank padding and truncation are specified for a string, the TI run-time environment might need to add an EBCDIC space character after a terminating SI character is added.
