Error Indicators and Warnings

NE_ALLOC_FAIL
Dynamic memory allocation failed.
NE_BAD_PARAM
On entry, argument value had an illegal value.
NE_CHARACTER
On entry, rname=value.
Constraint: rname must be called with rname=e04ufc.
NE_INTERNAL_ERROR
An internal error has occurred in this function. Check the function call and any array sizes. If the call is correct then please contact NAG for assistance.
NE_TOO_SMALL
One or more of the save array lengths is too small. Supplied values are: lcwsav=value, llwsav=value, liwsav=value and lrwsav=value.
