Re: Data validation, mapping, and error handling

Aaron,

I'll look into the FF on Linux problem.  Thanks for the tip.

The way to bypass auto validation is through data definition (DDS in the 
case of the sample I posted, although validation can also be defined 
using SQL DDL).  Remove the CHECK(ME) which means manditory entry, or 
RANGE(1  1000) parameters from the DDS, for example.

I agree the code is simple.  But I think it can get even simpler by 
encapsulating it in a generic SPECIAL file handler which could be used 
with any externally described file.  I plan on doing some R&D on that 
approach.  Drop wtnOpen() and wtnSetInst() and wtnRecGet() and 
wtnRecWrt() and wtnMsgWrt() and PLIST.

Do it with an "F" spec and READ and WRITE opcodes.

Nathan.
