Hi John,
Please find the answers as below:
Please describe exactly what the script needs to do.
This script splits the data from Detail files (i.e which are the input files for the shell script in .txt format) . In this case the detal file located at ${m_recv_dir}/${m_glb_d92_nm}${m_glb_file_seq} . which is the starting portion of the code which i posted.
This script reads the data line by line from the text file and prepare output .DAT file.
Once the .DAT file is created it puts '*/' end of file character at the bottom of the output file generated. Once the .DAT output file is generated another shell script loads data from this .DAT files to work tables of the database using SQL Loader.
What files does it use for input? What is the format of those files?
The format of the input file is .txt
What is the format of the output?
The output format is .DAT
Please do let me know what else information you need so you can help me on this..

NAME
cldump - Clarion database extractor
SYNOPSIS
cldump [options] database.dat
DESCRIPTION
cldump extracts the data contained in a Clarion database; Clarion is a Windows IDE similar to Delphi or others, and has its own (simple)
database format.
cldump can extract the data contained in such a database, and export it to CSV, SQL (including the database schema, keys and indexes) or
its own format (this format will give you all the meta information, but isn't easily parsable).
A Clarion database consists in a set of files :
.DAT files contain the data,
.Kxx files contain the key/index data,
.MEM files contain the memo entries associated to the data.
OPTIONS
-x n, --decrypt n
Decrypt an encrypted file. Required argument n indicates the location where the key will be retrieved. Valid values are in the range
1 - 4 inclusive. n = 1 usually works.
Decryption happens in-place so KEEP A BACKUP as there is no guarantee the decryption process won't fail. Encrypted files must be
decrypted before they can be dumped.
Note that only the data file and the memo file are decrypted in this process; key/index files are left untouched as cldump doesn't
use them.
-d, --dump-active
Dump active entries only
-D, --dump-data
Dump the actual data (active and deleted entries)
-m, --dump-meta
Dump meta information (no SQL or CSV output format exist for this option)
-f c, --field-separator c
Set the field separator to character c. Only valid for CSV output (see below).
-c, --csv
Dump data or schema in CSV format
-S, --sql
Dump data or schema in SQL format
-s, --schema
Dump database schema
-M, --mysql
Use MySQL specific construct (backticks, ...)
-n, --no-memo
Do not dump memo entries
-U[charset], --utf8[=charset]
Transcode strings and memos from charset to UTF-8 (charset defaults to ISO8859-1; for the list of supported charsets, see iconv
--list)
OUTPUT
cldump outputs the data to stdout or stderr depending on the output format selected, the data to extract and the type of the data (data,
meta data).
BUGS
The SQL output could be improved. Not all the types supported by the Clarion database format are implemented yet (due to lack of test data-
bases using these types of data); see the source code for details.
Please report bugs to jb@jblache.org; if possible, please send patches as the set of test databases I have is very limited.
