How to simulation keyboard stroke for following nums and operators: 0-9, A-F and point, + - x / %

Yes, I know to use isKeypressed(), but any chances for better solution?.

Thanks

[SOLVE] Never mind, I found a trick.

Code:
f = createForm()
f.setSize(500,100)
f.Position = 'poScreenCenter'
display = createLabel(f)
display.setPosition(20,20)
display.Font.Size = 16
input = createEdit(f)
input.setPosition(600,110)
input.Text = ''

keys = "0123456789ABCDEF.+-X/"

function start()
 input.setFocus()
 getKeyStroke()
end

function getKeyStroke()
 str = input.Text
 if str == "" then return nil end
 str = string.upper(str)
 if string.match(keys,str) then
  if display.Caption == "" then
   display.Caption = str
   input.Text = ''
  else
   display.Caption = display.Caption..str
   input.Text = ''
  end
 else
  input.Text = ''
 end
end

f.show()
start()
input.onChange = getKeyStroke


Note: except for escape character '%'

EDIT: solve for escape character.

Change this line

Code:
if string.match(keys,str)


To:

Code:
if string.find(keys, str, 1, true)
