Before using the INSERT command, some work does need to be done to make sure the name and format of the variables used in the inserted syntax are standardized across all data files with which you plan to use. birthdate, race, or major) are included in multiple data files. The INSERT command is useful to eliminate duplicated syntax and maintain standardized names, labels, and/or commonly derived variables when some of the same variables (e.g. Instead of duplicating the syntax in the syntax file for each data file, a smaller syntax file that only labels a variable and its values, for example, can be saved and then run by other syntax files with the INSERT command in SPSS. There are usually some of the same variables (gender, birthdate, etc.) included in multiple data files that your office collects or maintains.
