How can I set the alternate comment to be started by the first blank character after a given column?

In zOS assembler I would like to have comments as follows:

* starts standard comment
.* started non expanded comment
the first blank after column 15 starts inline comment

Is there a way to highlight all three types of comments?

tkx -- coder03

I think the following definition should work:
Note: There are 2 spaces after Line Comment Num = 1

With this definition any space character (not the tab character) in column 16 or later (up to 256) is interpreted as beginning of a line comment.

An asterisk found anywhere in a line is also interpreted as beginning of a line comment.

And .* found anywhere in a line is also interpreted as line comment.

For details on what can be used to define line and block comments see Template for Language File.
