To use the standard language file system for a file, identify the file with the SELECT clause as shown below.
SELECT file1 ASSIGN USING 'STL-MyFile'
If the runtime option FILESYS(STL) is in effect, identify the file as follows:
SELECT file1 ASSIGN TO 'MyFile'
If you have defined the environment variable MYFILE (for example, SET MYFILE=STL-MYFILE), identify the file as follows:
SELECT file1 ASSIGN TO MYFILE
