# C conversion
Read Time: 1 minute(s)
Concatenates fields, literals, and the results of a previous operation. It takes the general form:
- ; is optional. It has no function other than to provide compatibility.
- n can be one of the following:
- a field number (FMC)
- a literal enclosed in single quotes, double quotes, or backslashes
- an asterisk (*) to specify the last generated value of a previous operation.
- 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
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 (*) and then the content of field 2.
Concatenates the contents of field 1 with an asterisk (*), the string ABC, a space, field 2 a forward slash (/) and then field 3.
See the descriptions of the function codes (A, F, FS and their variants) for other concatenation methods.
