An array of strings, the sheet tab names, as unicode strings |
For more information about Unicode strings, see "Unicode Strings in BIFF8" on page 264.
Whenever possible, file names are encoded to make BIFF files transportable across file systems. Encoded file names are identified by the first character of the rgch field. The first character of the rgch field may be any one of the values listed in the following table.

Meaning |
|
chEmpty |
00 |
Reference to an empty workbook name (see text) |
|
chEncode |
01 |
File name has been encoded (see the following table) |
|
chSelf |
02 |
Self-referential external reference (see text) |
chEmpty indicates that the file name is an external reference to an empty workbook name, as in the formula =Sheet1!$A$1.
chSelf indicates that the file name is an external reference in which the dependent and source workbooks are the same. An example of this is the workbook SALES.XLS, which contains the formula =SALES.XLS!$A$1.
A chDDE key (03h) can occur in the rgch field; it is not necessarily the first character in the field, as are chEmpty, chEncode, and chSelf. This key indicates that the external reference is a DDE or OLE link. In a DDE link, the chDDE key replaces the | (pipe) character that separates the DDE application and topic. In an OLE link, chDDE separates the classname and file name.
A chEncode at the beginning of rgch indicates that the file name of the source workbook has been encoded to a less system-dependent file name. The special keys listed in the following table are recognized in the rgch field.

chVolume |
01 |

Represents a single-character volume name. Because single-character volume names are uncommon on the Macintosh, the chLongVolume key is used to represent volume names that are longer than a single character. |
|
chSameVolume |
02 |
Indicates that the source workbook is on the same drive as the dependent workbook (the drive letter is omitted). For example, |
Indicates that the source workbook is in the same volume as the dependent workbook (the volume name is omitted). |
|
ChDownDir |
03 |
Indicates that the source workbook is in a subdirectory of the current directory. For example, |
Indicates that the source workbook is in a folder in the current folder. For example, the formula =':XL:Sales1992'!A1 generates the chDownDir key. The folder name precedes the chDownDir key, and the file name follows it. |

The chLongVolume key is followed by the length of the name (1 byte) and then by the volume name string. | |
