how to adress the object name and not the number?

[Eric Chatonet]

Hi Bill,

As Jim said: using a space char is a personal programming choice, and  
certainly not a bad one ;-)
As for me, I prefer to name any object with a single word  
("LastBackupDate5" for instance) and *always* quoted even if XTalks  
don't make it compulsory in this case.
And to retrieve the right suffix, instead of using last word, I just  
use char x to -1:

char 5 to -1 of "Last1" = 1
char 5 to -1 of "Last1000" = 1000

No problem with the number of chars of the suffix ;-)
