Built-In Function Values

Values are supplied to a built-in function according to Parameters that are coded along with the function's invocation name. Parameters can be either string values or numeric values, as follows:

• A string value should be coded as an EBCDIC variable data field, a nonnumeric literal, or a built-in function that returns a string value. A value in a string built-in function cannot be zero in length and cannot be filled with only spaces.
• A numeric value should be coded as an arithmetic expression, a numeric variable data field, a numeric literal, or a built-in function that returns a numeric value.

Some built-in function parameters have restrictions on the values they can contain. If an invalid value is specified at runtime, the dialog aborts. For example, the value specified in a square root function must be positive.

If a parameter is specified with a different data type than expected, CA ADS attempts to make the appropriate conversion at runtime. The dialog aborts if the conversion cannot be made.
