The Quick Reference Guide states in part as follows:

Small Field Continuation Format 1:

You can enter + or * in the last field of a line and + at the beginning of the next line.

Small Field Continuation Format 2:
 

You can simply leave the continuation fields blank.

Small Field Continuation Format 3:

You can enter a unique character string in the last field of a line, then a continuation line begins with the same character string.

However it is noted that a combination of the above may be possible.

For example you can simply leave the continuation fields blank in the last field of a line and + at the beginning of the next line.

Other combinations may be possible.
