To underline text defined on g statements, type:

after the last g statement in a block. n is 1 to underline the whole text, 2 to underline everything apart from blank strings, or 3 to underline non-blanks only.

Text on g statements can be underlined by placing a u statement immediately after the last g statement in a block. The format of the u statement is:

where n is 1, 2 or 3 and defines the type of underlining required:

These correspond to unl1, unl2 and unl3 on n, col, val, fld and bit statements.

Here is are the spec and table from the previous section updated to include underlining:

This produces:

If u does not meet your needs, you can enter your own underlining on a g statement with hyphens in the appropriate places. This is often useful in complex breakdowns using categories from more than one axis.

For example:

If you want to convert the tables to a comma-delimited ASCII file using the program q2cda, you might want each column in the column heading to be treated as a separate text (the default is to treat each line as a single text). If so, you must underline the column texts, and each set of underlining must extend the full width of the column. Do not, however, use u for this type of underlining. Use = or – characters on a g statement instead since it is these characters, rather than the underlining character, that q2cda uses for finding the start and end of each column.
