Some variables are flagged incorrectly as not being written to

Referring to the code at #29:
The warning:
Warning:volterra_627.f:415,39:
Variable 'U' read but never written
DOUBLE PRECISION RELERR, ABSERR, U, DIFF, K, G, FX
indicates that the analysis of read/write actions is not quite waterproof: the variable in question is set in the subroutine VE1 (line 740 of the source file). Indeed it is not set in the calling program unit.

Issue fixed with commit f9e5ffd
We now have a specific structure for function and subroutine call arguments, and we mark subroutine arguments as possibly used as we can't really know if they are written to in the call.
