Concatenates fields, literals, and the results of a previous operation.
; is optional. It has no function other than to provide compatibility.
n can be one of the following:
x is the character to be inserted between the concatenated elements. If you specify a semicolon (;), no separator will be used. Any non-numeric character except a system delimiters (value, subvalue, field, start buffer, and segment marks) is valid.
Input conversion does not invert. The concatenation is applied to the input data.
Concatenates the contents of field 1 with field 2, with no intervening separator character.

Concatenates the contents of field 1 with an asterisk (*), the string ABC, a space, field 2 a forward slash (/) and then field 3.
