Change Font size in RichText Datawindow 1 column

Question

Running PB 12.1  Classic.
Whatever I do; font size does not want to change in a Richtext presentation style external datawindow size of column = string 20000000 bytes
Why = long story - converting unix reports to PB for Archiving.
I do this after the only column is populated.  You can actually see all text
dw_1.SelectTextall()     Actualy selects ALL text in dw
I have tried to setColumn(1) returns -1
src = dw_1.Modify("a.Font.Height='-8'")      a = column name     Line 1  Column 15: incorrect syntax.
li_rtn = dw_1.SetRichTextSize(8)    li_rtn = -1
I could use 2 datawindows with different Font sizes but I would like to know how can I accomplish this with code.
Anything else works
src = "DataWindow.Print.Orientation='1'
src = dw_1.Modify("DataWindow.Print.PrinterName='Xerox Phaser 5500DX PS Tray 3'")
src = dw_1.Modify( "datawindow.print.preview=yes" )
ls_default_printname = dw_1.Object.DataWindow.Print.PrinterName
li_PageCount =  long ( dw_1.describe  ("evaluate('pagecount()'," + string ( dw_prt.rowcount() ) + ")"))
src = dw_1.Modify( "datawindow.print.preview=no" )
ls_page_range =dw_1.describe ( "DataWindow.Print.Page.Range" )
li_noCopies =  integer( dw_1.describe ("DataWindow.Print.Copies"))
src = "DataWindow.Print.Copies='" +String(astr_spool.copies)+"'"
src = dw_1.Modify( src )
src = "DataWindow.Print.duplex='" + String(astr_spool.duplex)+"'"
src = dw_1.Modify( src )
src = "DataWindow.Print.paper.Source='2'"
src = dw_1.Modify( src )
dw_1.Object.DataWindow.Print.PrinterName= 'Sybase Datawindow PS'

Luis,
Not according to the examples in PB help under the Controls in a DataWindow and their properties section. While there are no specific examples for Font.Height, there are for other properties expecting numeric values
ie (copied from PB help) -
dw_1.Modify("emp_name.X=10")
dw_1.Modify("empname.Height=50")
dw_1.Modify("emp_stat.Protect=1")
dw_1.Modify("DataWindow.Print.Margin.Top=500")
etc
None of the examples I've seen use quotes around the property value where the value is expected to be numeric.
Although, like I said, I've seen Modifys using numeric arguments work both with and without quotes.
The setColumn(1) returning -1 is a concern. Seems to indicate there's something fishy going on ... wonder what happens if you try SetColumn with the column name. What event/function is this code executing from?
