I have many data files needing to be parsed and reformatted. The parsing
is easy using the print statement, but I'm struggling to find an awk string
manipulation function that reformats each field. Reading "Effective awk
Programming, 4th Ed." leaves me uncertain whether to use sub(), gsub(),
gen
Have you considered: man awk ?
You probably want to look at substr().

I missed that one, Russell. I'll try it to figure out how to insert
characters at specific places.
Thanks,

Thanks again, Russell. I now have a one-liner:
{ print substr($1,1,4)"-"substr($1,5,2)"-"substr($1,7,2),
substr($2,1,2)":"substr($2,3,2), $4 }
That produces:
1988-10-01 00:30 0.75
1988-10-01 01:00 0.75
1988-
