Hi Klass

Thanks for your comments, however it appears that neither
CCP4_PARSER_MAXLINELENGTH nor CCP4_PARSER_MAXFILENAMELENGTH are actually
used in the CCP4 parser code now. I think that they were left over from
the initial implementation (I will clear them out for future releases),
and my understanding is that the core parser library now allocates
sufficient memory to accommodate the lines that are passed in from the
calling subprogram.

The problem with long file names has been reported to us at CCP4
independently and is being investigated, but I don't know the current
status. So I'll ask the appropriate person to get in touch with you.

Best wishes

Peter
