UC - Underlining Character

This session parameter determines the character that is used as underlining character for the following:

column headings generated by DISPLAY statements;
page titles/trailers produced by WRITE TITLE / WRITE TRAILER statements with UNDERLINED option.

Possible settings	any character	See also Note.
Possible settings	`OFF`	See also Note.
Default setting	`-`	Hyphen (-).
Specification within session	yes
Applicable statements	`DISPLAY` `FORMAT` `WRITE TITLE` `WRITE TRAILER`
Applicable command	none

Note:
If you do not wish column headers to be underlined, you have the following options:

`UC=`	A blank line will be output instead of underlining.
`UC=OFF`	The field values will be output immediately below the heading line, without any blank line in between. You can specify `UC=OFF` only at the statement level of a `DISPLAY` statement; in this case, you cannot make any other `UC` specifications for individual fields in that statement.

FORMAT UC=* 
DISPLAY (UC= ) NAME AGE (UC=+)
