ALTNAME (Alternative Record Name) keyword for display files
You use this record-level keyword to specify an alternative name for a record.
The alternative name can be specified for I/O operations when using program-described files. The syntax of the alternative record name must be valid for the high-level language compiler in use.
The format of the keyword is:
ALTNAME('alternative-name')
See System/36 environment considerations for display files for information about how to specify the ALTNAME keyword.
