Subject: Re: [APDL] *vread with mixed character/number array.
Author: John Swanson
Date: 2002-08-22 14:54:00

My immediate thought was "Nope, can't do that because ansys uses the
system read with the
user supplied format statement". However, the clever suggestions contained
here might offer some
hope, especially with the c formats.
Can someone help me understand better what is desired. Is it as simple
as ignoring any lines
which contain characters? Or do we need to ignore lines which contain
characters in columns which
are supposed to contain numbers? If we were to read the entire line as a
character string, then
decode it internally, what would the maximum line length be? Would a fixed
limit like 128 of 640 (slower)
be acceptable?
Comments, anyone?
