Time-Edit Variables

Deprecated Since Version 15.0.0: Coding lost.

A record is automatically made every dump cycle of the values of the following non-zonal “time-edit” variables. These records are stored in the second half of the ‘.lib’ file and are accessed by the timeplot and look commands (see Chapter XXX). There are nine dummy variables holding space for future time edit variables, but even more could be added if the value of LENTDUMP in DUMPQ were increased.
