gnubol: Compiler Limits

[RKRayhawk@aol.com]

Someone in here said that there are no limits to the number of WHEN clauses 
in an EVALUATE statement.  Is that what the standard says.

A notable mainframe vendor sets two limits relevant to this
 
 EVALUATE subjects are limited to 64, that would in effect be 63 ALSO clause 
plus one leader. And the EVALUATE WHEN clauses  are limited to 256.

Seems like with an eight bit character code you cannot possibly have a lower 
limit on the WHEN clauses. Does anybody have information on other vendors?  
Do any of the UNIX compilers actually limit EVALUATE WHEN clauses to 128 
(ASCII theoretically a seven bit code.

I am not saying that these kinds of factors can be used to disambiguate 
nested statements of any kind, just trying to get the compiler limits 
discussion started.

The when subjects is certainly an intersting factor. 

What other limit factors could relate to discussions of the parser or the 
syntax to semantics interface.

Best Wishes,
