Global Data Change (GDC) documentation suggests that items in fixed (control) fields can be changed using GDC - for example, changing "type of record" and "bibliographic level" in the leader. Is this something that can be changed?
Yes. There's a consequence called "Replace String At Position" that lets you specify a byte in a fixed (control) field and enter a new value for it.
This applies to fixed fields in both Bibliographic and Holdings records.
For example, if you wanted to update "type of record" to e for a set of records, the consequence would look something like:
Consequence: Replace String At Position
Control Field: LDR
Replace String at Position: 06
With string: e
Be aware that Global Data Change will not verify the new string is valid encoding, so be mindful of that.
MARC fixed fields are 0-indexed - positions start at 0, not 1. See the GDC User's Guide for details.
