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')
Refer to Appendix F, "System/36 Environment Considerations Using DDS", for information on how to specify the ALTNAME keyword.
