[Gambas-user] Format Text

[Rolf-Werner Eilert]

Hi,

Can you quote the thing you've written? Maybe you missed something or 
so... Normally it should work with both len() or string.len()

Ok, then you said you will only give strings to another program, so the 
font shouldn't be important. In Basic, the only way of doing what you 
want will be using Print with a comma:

print "22.55", 'the comma adds a tab character chr$(9)

Then I remember (was it PowerBasic?) a "USING" thing where one could do 
such things with a mask of "###" or so. Long time ago, very, very long 
time ;-) Never used that stuff then.

But as you need right-aligned tabs... you will need to spend a little 
time developing an algorithm that assembles your lines.

You mentioned other languages that offer easier ways. Can you give me an 
example? The easiest way I can think of would be some function where you 
define the line length and the tabs and then you add the strings to be 
inserted. If this function just replaces a line of spaces with the 
inserted strings, it wouldn't be too complicated.
