Recoding: search and replace

[Richmond]

I wonder if there is a way to replace this:

set the unicodeText of fld "fDECODE" to (numToCodePoint(107) & 
numToCodePoint(104))

with this:

*put (numToCodePoint(107) & numToCodePoint(104)) into fld "fDECODE"*

where /(numToCodePoint(107) & numToCodePoint(104))/ vary?

I have no great urge to do that sort of thing manually about 6 million 
times.
