Deferred evaluation?

[Raymond Chitolie]

Second query of the day, I hope I am not pushing it!

To properly explain my problem, maybe I should describe what kind of
program I am creating...

I am having difficulties in trying to get the most current value from
a variable, which refers to another variable, like so...

set dialogue(SE,1,default) "Default"
set dialogue(SE,1,value) "$dialogue(SE,1,default)"
set dialogue(SE,1,parm) {-I$dialogue(SE,1,value)}

SE,1,value is used as an entry widget's text variable, so for example,
if the user modified the contents to be "Standard", the desired output
would be:

-IStandard

The reason of having the default section at all, is so I have the
means to reset the values when required to nominal defaults.

The problem is that when processed (for testing purposes, using puts
stdout), the following occurs...

-I$dialogue(SE,1,value)

In other words, exactly as what is kept in the braces. How can I force
the command to work as I want? I have kind of got round it by using
the following...

set dialogue(SE,1,parm) {set tmp "-I$dialogue(SE,1,value)"}

With this inelegent solution, the set value merely returns the correct
value at the time $dialogue(SE,1,parm) is called.

Is there a better solution?

Any help provided in this matter would be gratefully appreciated.
Access to this group is not reliable for me, so E-Mail straight to me
as well as this group would be a big help. Thanks!

Be seeing you...

Note that the 'set' command can be used to return the value of a
variable. With this in mind, you can do this:

set dialogue(SE,1,parm) "-I[set dialogue(SE,1,value)]

This should provide what you want.
