With this session parameter, you can specify leading characters that are displayed immediately before a field output by a DISPLAY statement. The width of the output column is enlarged accordingly.

Possible settings	any character	Up to 10 characters may be specified. Notes: Leading characters may optionally be specified enclosed within apostrophes, in which case, any characters can be specified. Any character string specified which contains a closing parenthesis or a quotation mark must be enclosed within apostrophes. A circonflex (^) is used to represent a blank in a character string not enclosed within apostrophes.
Default setting	none
Specification within session	yes
Applicable statements	FORMAT	Parameter may be specified dynamically with the FORMAT statement.
	DISPLAY	Parameter may be specified at statement level and/or at element level.
Applicable command	none

Notes:

1. The session parameter LCU is identical to the session parameter LC. The difference is that the leading characters are always stored in Unicode format. This allows you to specify leading characters with mixed characters from different code pages, and assures that always the correct character is displayed independent of the installed system code page.
2.  The session parameters LCU and ICU are mutually exclusive.
