List of Parameters

The data transfer attribute configuration parameters are shown in this section.

XCOM--COMPRESS

Indicates the compression type. When communicating with an IBM mainframe, if the data file contains any empty lines, COMPRESS can only be set to YES, LZSMALL, LZMEDIUM, or LZLARGE.

Notes:

• Not all compression types are supported on all platforms. For supported compression types, see the partner platform documentation.
• The LZ values enable LZ (Lempel-Ziv) compression to replace sequences of data bytes that occur more than once in a data stream with a code value.

COMPACT

RJE compaction algorithm optimized for uppercase English text.

LCOMPACT

RJE compaction algorithm optimized for lowercase English text.

LZLARGE

Activates LZ compression to search back 32K in the datastream for a matching string.

LZMEDIUM

Activates LZ compression to search back 16K in the datastream for a matching string.

LZRW3

General-purpose algorithm that runs fast and gives reasonable compression.

LZSMALL

Activates LZ compression to search back 4K in the datastream for a matching string.

NO

Indicates no compression.

RLE

Run length encoding.

YES

Indicates run length encoding of binary zeros and blanks only.

ZLIBn

Greater compression than LZRW3 but less than LZSMALL, LZMEDIUM, and LZLARGE. The n value can be 1 through 9.

Default: YES
