/ Program   : titlegen.sas
/ Version   : 1.0
/ Author    : Roland Rashleigh-Berry
/ Date      : 28-Sep-2008
/ Purpose   : Spectre (Clinical) macro to generate titles and footnotes from a
/             dataset of the style created by the %crtitlesds macro.
/ SubMacros : none
/ Notes     : You would normally select from the dataset created by %crtitlesds
/             macro and add special headers and footnotes if required and then
/             pass the resulting dataset to this macro so that the titles and
/             footnote statements get generated.
/
/             If there is a variable named "length" in the input dataset then
/             the value in it will be assumed to be the text length. This is
/             useful when there are deliberate trailing spaces in titles and
/             footnotes.
/
/ Usage     : %titlegen(dsname)
