Salut Nigel,

try to go with gb.eval
like this:

' Gambas module file
PUBLIC SUB Main()
DIM hExpression AS NEW Expression
  PRINT "use gb.eval"
  PRINT "    hExpression.Text = ' 10 + 11 + 53'"
  hExpression.Text =" 10 + 11 + 53"
  PRINT "    hExpression.Text result = " & hExpression.Value
  PRINT " and see also Examples/Evaluator "
  STOP
END


This is not as powerfull as Clipper 'Macros' was, but it is a beginning.

Amicalement
