Carlos,
By saving one line of code you are increasing the maintence complexity of your code by an order of magnitude. You are also making it a lot harder to debug. These ought to be reason enough to prevent you from trying to do this.
I rarely commit code to paper any more, one reason for this is that by using object methods that are relatively short there just isn't as much need to print code as there was in the days when everything was one huge .prg file.
For the times that I do want to get a good look at a section of source code I use a two column landscape report form that prints the code out at 12 lines per inch using Courier New 6 pt. This lets me see 190 lines of code on a single sheet of paper.
>Hello to all, How can write two o more instructions in one line of code, for example :
>* I want see this program in two line of code
>select('Mytable'), set order to ('MyIndex'), go top
>X=1, Y=2, Z=3

>This save papersheetand make less line of code...
