Extended parameters of the module *ZIP

Select the *ZIP module by entering option number 8 into the corresponding choice box. In the dialog program "Change i-effect Module Data", parameters can now be modified.

The following parameters can be defined for the *ZIP module:

*ZIP Defaults:

Max. Lookahead for *AUTO

The maximum lookahead defines how many bytes are to be read from the decompressed data stream when determining the record length of a file (OUTRECL(*AUTO)). The larger the number of bytes, the longer it takes to automatically determine the record length.
Default value:

0	The default value is 0 (read the entire data stream). If large files with definite record structure are processed, it is recommended to limit the value in order to improve runtime.

Compatible with gzip 1.2.2

Determine if gzip files are generated in a format compatible with older versions of gzip. Version 1.2.2 does not support file comment fields, which are suppoted by version 1.2.4. and higher.
Possible values:

*NO	Create gzip files in the current format of version 1.2.4 and use file comment field
*YES	Create gzip files in an older format. This is required to open i-effect^® files with older gzip or WinZip versions, or other unpacking applications.

Default Output Path

This parameter defines the path where files generated with this module will be stored this path automatically if the variable %DEFAULTPATH% is used in the OUTPFILE parameter of the CVTSPLXXX command.

CODE

Default: /i-effect//spool/out

ZIP Standards for Compression before Sending:

Create ZIP Archive?

Determine if a ZIP archive will be created to archive outbound data.
Possible values:

*NO	No ZIP archive is created for archiving.
*YES	A ZIP archive is created for archiving.

Compression Rate

With this parameter the relation between optimal compression speed and maximum compression is managed. This relation is balanced in the default setting. Using value 1, the program achieves the highest speed but maximum compression will not be achieved. Using value 9, maximum compression is achieved but the program runs at a slower rate.
Default value:

3	Values between 0 - 9 are valid. 0 = no compression; 9 = maximum compression.

Use Original Name?

The original name of the input file can be output into the compressed output file. Therefore, i-effect^® uses the name of the input file member. This name can be used for decompression in order to restore the file with exactly this name. (In this version the name can indeed be used for compression, but when decompressing the name is merely stored for information purposes in the file member text of the generated file member.)
Possible values:

*NO	The original name of the input file member is not stored.
*YES	The original name of the input file member is stored in the compressed output file.

Enter CRLF ?

In order to enable the recipient to recognize the record structure of the original file, control characters for carriage return and line feed (CRLF) can optionally be inserted at the end of each record.
Possible values:

*NO	Data remain unchanged for input and compression
*YES	The control characters EBCDIC X'0D25' or ASCII X'0D0A' are inserted at the end of each record.

Delete Subsequent Blanks ?

When processing a file for compression, i-effect^® may delete all subsequent blanks at the end of each dataset. In connection with the parameter CRLFINSERT, this may be used to have the last character of a dataset followed by a record control character, which is not a blank.
Possible values:

*NO	Blanks at the end of a dataset will NOT be deleted.
*YES	All blanks at the end of a dataset will be deleted.

From CCSID ?

The code page number of the source system.
Possible values:

*JOB	i-effect® uses the job's CCSID.
Number	The CCSID's number.

To CCSID ?

The code page number of the target system.

*JOB	i-effect® uses the job's CCSID.
Number	The CCSID's number.

Naming the Archive Entry

Enter the name of the archive entry.

*DEFAULT

Format for Filenames

Enter the default format for filenames. When storing the file in the archive, the file is built as follows.

*FILE	The name of the archive file is identical to the name of the input file
*MEMBER	The name of the archive file is identical to the name of the input file member.
*NAMEFMT0	The name of the archive file corresponds to the following format: library/file.filemember
*NAMEFMT1	The name of the archive corresponds to the following format: QSYS.LIB/library.LIB/file.FILE/file member.MBR

ZIP Standards for Decompression after Reception:

From CCSID ?

The code page number of the source system.

*JOB	i-effect® uses the job's CCSID.
Zahl	The CCSID's number.

To CCSID ?

The code page number of the target system.

*JOB	i-effect® uses the job's CCSID.
Zahl	The CCSID's number.

Record Length Output File

This parameter defines the record length of the output file.

*AUTO

Using this setting, the input file's record length is automatically used for compression. If inserting additional control characters is activated in parameter "CRLFINSERT", this will be considered when determining the record length. The decompressed data will be analyzed during decompression if *AUTO is selected. If record control characters (CRLF) are found, the output file will be stored with the record length that is necessary to store all datasets. (The length of the longest record will be used for the file.)

Number

Record length

Output Library

Enter the name of the library for output files.

*STD	Default value.
