Default External Functions

The two external functions CA 2E automatically creates are:

• An Edit File (EDTFIL) function

  This type of function maintains multiple records on the file. An example in this tutorial will be the Edit Course function.

• A Select Record (SELRCD) function

  This type of function provides a display of the records on the file, and allows the selection of one record for return to a calling program. An example in this tutorial will be the Select Course function.

Both of these external functions are interactive device functions. Note that CA 2E does not automatically create these device functions for capture files (CPT).
