Work with source files

These topics describe how to enter and maintain data using various methods.

• Use the source entry utility (SEU)
  You can use the source entry utility (SEU) to enter and change source in a source file. SEU is part of IBM^® WebSphere^® Development Studio for iSeries™.
• Use device source files
  Tape and diskette files can be created as source files. When device files are used as source files, the record length must include the sequence number and date fields.
• Copy source file data
  The Copy Source File (CPYSRCF) and Copy File (CPYF) commands can be used to write data to and from source file members. When you are copying from a database source file to another database source file that has an insert trigger associated with it, the trigger program is called for each record copied.
• Load and unload data from non-iSeries systems
  You can use the Copy From Import File (CPYFRMIMPF) and Copy To Import File (CPYTOIMPF) commands to import (load) or export (unload) data from and to a non-iSeries™ system.
• Use source files in a program
  You can process a source file in your program. You can use the external definition of the source file and do any input/output operations for that file, just as you would for any other database file.
