One approach that may work for determining the amount of text to show is:

put empty into fld tryOnForSize
repeat for each line LNN of veryLargeTextBlock
  put LNN & cr after fld tryOnForSize
  get the formattedheight of fld tryOnForSize
  if it  > the height of fld tryOnForSize then exit repeat
end repeat
put line 1 to -2 of fld tryOnForSize into fld vizDisplayFld
