[OPEN-ILS-GENERAL] MARC batch edit for fixed length fields?

[Janet McGowan]

Hi,
I've been using the MARC batch edit function fine for overlaying 
variable tag data, but I wonder if it should be possible to use it for 
batch editing specific positions in control data - in fields like the 
LDR or 008?
For example I have been trying to change a code in the character 
position 23 of the 008 (Form of item) from one code to another. I've 
been able to overlay the whole 008 by entering spaces to identify the 
position, but this overwrites the whole string. Could anyone advise me 
if there is there a syntax that I could use in the MARC Data part of the 
rule to identify the position to be changed?
Thanks for any help you can offer,
Janet
