Concatenation

The *CONCAT built-in function provides the means of joining or concatenating two discrete strings of data into a single string.

For more information on concatenating numeric data without conversion to character data, see this topic, Convert Variable.

There are four parameters for this function type.

• Three input parameters: a character field, *String 1 of usage VRY which is the first string to be joined; a character string, *String 2 also of usage VRY which is the second string to be joined to *String 1; and a numeric field, *Number of blank, that determines the number of blanks between the two strings.

  The following three conditions are supplied with the *Number of blanks
  parameter.

• One output parameter, which is the *Resulting string or the string that comprises the two joined strings

CA 2E implements the *CONCAT built-in function as an RPG CAT statement. In COBOL CA 2E implements the *CONCAT function as a STRING statement.

The following example shows a concatenation function that concatenates the fields Name and Last Name and does not put any blanks between the two strings.
