The grg program internally limits the size of a number of buffers. These
are listed here with their default maximum sizes. Exceeding the given sizes
will produce a fatal error. In some cases writing the GRG file in
a slightly different way will solve the problem, in others it will not. In
the latter case the relevant values must be increased in the source code and
the grg program recompiled. The following limits are all maximums and
size is size in characters unless specified otherwise.
A number of the static buffers in GRG have been rewritten to scale dynamically and hence have no fixed limit anymore. These are indicated by the asterix against an entry below. You can get more information by looking at the debug output under the operating limits section.
