PARSER VERSION NUMBER: 3.2.8

PLATFORM (SPARC, HP700, PC, etc.): PC

OS AND VERSION: Windows 2000 Version 5

REPORTED BY: Jim Bell, SiQual Inc.

DATE: 1/17/02

DESCRIPTION OF BUG: Truncation of long File_name generates new errors.

When IBISCHK3 detects a File_name that is too long, the truncation of the 
file name down to the legal size often results in new errors being generated:

	1.) "File name opened 'original_file_name.ibs' not the same as File_name 
'truncated_file_name'"

	2.) "File_name 'truncated_file_name' must contain one period."

Error number 1 is reported because the File_name truncation occurred before 
the two file names were checked for equality. This can be remedied by 
checking the file names for equality before testing for File_name length.

Error number 2 is generated because IBISCHK3 truncates the File_name 
starting on the right moving towards the left, almost always deleting the 
'.ibs' extension in the process. It is important that IBISCHK3 preserve the 
.ibs extension in the File_name when attempting to truncate down to the 
legal number of characters. There are two choices for fixing this problem:

	1.) Don't try to truncate the File_name (recommended). Report the error, 
but leave the File_name as is.

	2.) Do a better job of truncating the File_name. Do two truncations, 
preserving the .ibs extension in between.


The following is the report generated when the example file was checked 
with IBISCHK3 v3.2.8.
