Re: Type Casting

[Doug Donalson]

Just for your info, the reason I am doing this is that each 2-D grid
site in my model is a sub-population of a metapopulation and I need
to instrument each one as well as the model global output.  As opposed
to making one HUGH file, I am using the x,y's of the cells to create seperate

file names for each cell.  (Then I will just have around 440 files per run!)

but it doesn't, it outputs "got 1" but I realized what I did
wrong.(char)(1+48).  It's been a long time since I did anything at this
level.
Sigh... I'm losing my touch.

That's correct, I change the definition to a protocall as per above andused
the above statement to create it.  BUT:

[string appendC: "someAdditionToString"]

gets a message that String doesn't recognize appendC:

This is not critical to my app any more but it is bothersome none the less.
