In fact, there is no reason to limit the usage to SPECS:
"... | pick w3 == var Fred | ... "
"... | strnfind var Fred | ..."
"... | insert var Fred | ..."
For extra fun:
"... | specs ... substr w3 of var Fred nf ... | ... " /* Write
third word of Fred as next field. */
And
"... | locate 41.80 substr 10.3 of var Fred | ..." /* Look for
chars in 10-12 of Fred in pos 41-120 of record */
Thinking about 'TRACKING' gives me a headache, but it could be useful in
some situations, and confusing in others. Could the keyword 'TRACKING'
be used to control it...?

It would be the same as the second case (x"c2x(Fred)"), less
conversions. The value of the Fred would be at the value stored in the
output buffer at the specified location. Blanks would be honored, since
the parser would not look at the data anymore than it looks at the data
in 1-*.

Hobart, What happens here if "fred" contains one or more imbedded
blanks?
