Description:
We are trying to copy the RLIN 852 field to a 950 field while preserving the original 852 field:

This is the rlin.fix "generic fix" we are using:

1 852## COPY-FIELD 950
1 950## CHANGE-SUBFIELD b,l
1 001 COPY-SYSTEM-NUMBER 0359 ,L,a,(CStRLIN)
1 001 DELETE-FIELD 001

Resolution:
The "Generic Fix Doc Script Specification" says: "(If it is necessary to duplicate a field, tag and all, first COPY FIELD to a temporary tag, then CHANGE FIELD to the desired tag.)"

Changing the first line in the script to use the temporary tag "999" and inserting a CHANGE-FIELD line worked:

1 852## COPY-FIELD 999
1 999## CHANGE_FIELD 950
1 950## CHANGE-SUBFIELD b,l
2 950## COPY-FIELD 852
2 001 COPY-SYSTEM-NUMBER 0359 ,L,a,(CStRLIN)
2 001 DELETE-FIELD 001
