As to part 2 of the question....eval is a replacement operation no clear
is needed prior to the eval.

your divide by two could result in an intermediate answer with decimal
positions.

decimal positions are invalid for the param of %subst()

try this

d $beg      s                  3s 0

C eval   $beg = (%size(Title) - (%size(%trim((cTitle)) / 2)

C   eval  %subst(Title:$beg) = %trim(ctitle)
