MAP Subcommand (MATCH FILES command)

MAP produces a list of the variables that are in the new active dataset and the file or files from which they came. Variables are listed in the order in which they appear in the resulting file. MAP has no specifications and must be placed after all FILE, TABLE, and RENAME subcommands.

• Multiple MAP subcommands can be used. Each MAP shows the current status of the active dataset and reflects only the subcommands that precede the MAP subcommand.
• To obtain a map of the resulting file in its final state, specify MAP last.
• If a variable is renamed, its original and new names are listed. Variables created by IN, FIRST, and LAST are not included in the map, since they are automatically attached to the end of the file and cannot be dropped.
