What's the opinion on global vs. local error codes. By global I mean a
central list of codes in an include file. By local I mean a list of 
codes which is meaningful only in the context of the procedure which
returns the code.

A central list can be difficult to maintain but it is nice to have
only one place to look for error codes. On the other hand local 
codes can be sequential and allow one to use "FORTRAN: computed
gotos" :-)
