Subject: Re: [APDL] *vread with mixed character/number array.
Author: Gordon May
Date: 2002-08-22 09:38:00

One option would seem to be to read the data into a character array:

*dim,textdata,CHAR,xsize,ysize,zsize
*dim,numdata,ARRAY,xsize,ysize,zsize
*vread,textdata(1,1,1),filename
(1A8)

and then use

numdata(x,y,z) = VALCHR(textdata(x,y,z))

to convert back into numerical data. I don't think there's a quick vector
operation to do this, so it could be VERY slow if your arrays are large...
and of course there's the problem if your numerical data is not fully
contained within the first eight characters of each input record :-(

Dave, Peter,

No, the characters may not always be the first group of lines. NSKIP
doesn't work in this case.
