FILE Specification (MATRIX-END MATRIX command)

FILE designates a matrix-format data file. See MATRIX DATA for a discussion of matrix-format data files. To designate the active dataset (if it is a matrix-format data file), use an asterisk, or simply omit the FILE specification.

• The file reference can be either a filename enclosed in quotes or a file handle defined on a FILE HANDLE command that precedes the matrix program. The file reference cannot be the name of a dataset in the current session.
• The same matrix-format data file can be read more than once.
• If you omit the FILE specification, the current active dataset is used.
• MGET ignores the SPLIT FILE command when reading the active dataset. It does honor the split-file groups that were in effect when the matrix-format data file was created.
• The maximum number of split-file groups that can be read is 99.
• The maximum number of cells that can be read is 99.
