Parameters

default If you specify the default parameter for the set useSourceColumns command, the current document will use the value of default.useSourceColumns.
on If you specify the on parameter for the set useSourceColumns command, the current document will use column characteristics of the file in its source encoding. If you specify the on parameter for the set default.useSourceColumns command, all documents that have useSourceColumns set to default will use column characteristics of the file in its source encoding.
off If you specify the off parameter for the set useSourceColumns command, the current document will use column characteristics of the file in its Unicode encoding. If you specify the off parameter for the set default.useSourceColumns command, all documents that have useSourceColumns set to default will use column characteristics of the files in their Unicode encoding.
install If you specify the install parameter for the set default.useSourceColumns command, all of the documents that have useSourceColumns set to default will use the value of install.useSourceColumns.

Description

By default, column-related editor settings are in terms of Unicode characters. The useSourceColumns parameter changes this to bytes for DBCS/MBCS (double-byte/multibyte character set) source character encodings, in order to better emulate the editing of host files in their native environment. If the source encoding of the file is not DBCS/MBCS, this parameter has no effect. The following editor settings may be affected by the value of the useSourceColumns parameter:

the displayPosition parameter
the fields parameter
the save.textLimit parameter
the sequenceNumbers parameter
the "Column" field displayed on the status line
the current position displayed on the format line
tabs expansion.
