Using the CONVERT() function in program

[Carlos295pz]

INPUT can force you to type the unit on the data entered, but this can be annoying and slow

Code:

INPUT({{var,[9]}})

A more friendly alternative would be to indicate the unit in the label or help.

Code:

  INPUT(var,{},"Long (km):");
  var:=var*1_km

You can also achieve something more interactive with a selection of the unit

Code:

  LOCAL var,und={"mm","cm","m","km"},un;
  INPUT({{var,[0],{20,20,0}},{un,und,{42,15,0}}},{},"Long:");
  var:=EXPR(var+"_"+und(un))
