Eva,

The number of values that can be -post-ed (ie. number of items in your 
`topost' local macro) depends on the current -matsize- (that's documented 
somewhere, but don't ask me where...) 

Not sure this is causing the error you get (but fairly likely I guess): 
just -set matsize xxx- before running your program, where xxx is larger 
than your current value.

Hope this helps,

Philippe.

This is a bit difficult to debug in the absence 
of part of the program. You could 

. set trace on 

and see where it all blows up.
