$VIB

$VIB group (relevant for RUNTYP=HESSIAN, METHOD=NUMERIC)

Formatted card image -restart- data. This data is read in the format it was punched by a previous HESSIAN job to the file IRCDATA. Just add a " $END" card, and if the final gradient was punched as zero, delete the last set of data.
Normally, IREST in $CONTRL will NOT be used in conjunction with a HESSIAN restart. The mere presence of this deck triggers the restart from cards. This deck can also be used to turn a single point differencing run into double
differencing, as well as recovering from time limits, or other bombouts.
