Defining Function Parameters

The Edit Function Parameters panel lets you specify parameters for a function in one of two ways:

• You can specify individual fields as parameters by typing the keyword *FIELD under File/*FIELD and typing the field name under Access path/Field. In the Passed as column, type FLD to indicate that each field is passed as an individual parameter.
• You can specify a set of fields from a file by typing a file name under File/*FIELD and the name of an access path based on the file. In the Passed as column, type one of the following.
  • RCD to indicate that all the fields from the access path are to be passed as a single parameter. KEY to indicate that only the key fields from the access path are to be passed as a single parameter.

  In this case, you can zoom to display the Edit Function Parameter Details panel to select fields from the specified access path.

You used the *FIELD method to specify parameters earlier in the tutorial when you defined error message functions for the Edit Horse function. In this topic you will use the access path method.
