Hi Giedrius,
For VFP 254 is Character type field limit not string limit. A VFP string can be as large as 2 Gb and command line 8192 bytes. Virtually this means you could have a 2Gb string at a command line (no macro substitution).

*A sample for a form with a oleboundcontrol
#DEFINE TAB CHR(9)
#DEFINE CRLF CHR(13)+CHR(10)
THIS.LockScreen = .T.
M.CGDATA = ""
for ix=1 to 2000
    m.cgdata = m.cgdata+TAB+"val"+str(ix)
endfor
m.cgdata = m.cgdata +crlf+"Value"
for ix=1 to 2000
  m.cgdata = m.cgdata+TAB+str(ix)
endfor
wait window str(len(m.cgdata))
create cursor foo (gen1 g)
append blank
append general gen1 class "msgraph.chart" DATA M.CGData
THIS.OleBoundControl1.ControlSource = "Gen1"
THIS.OleBoundControl1.HasLegend = .t.
*THIS.OleBoundControl1.autoformat(14, 1)
THIS.LockScreen = .F.

The above code would produce a 50007 bytes m.cgdata (Do not run the example if you don't have a fast computer - lower the 2000 value first).
