Any ideas on what this is referring to or how to correct it?

It seems to be related to the following:

proc run {filename} {
set base [file rootname $filename]

set as400 $base
append as400 ".sql"
set hsql $base
append hsql "_hsql.sql"
set insert $base
append insert "_insert.java"
set update $base
append update "_update.java"

set arg [getNewFlag $base]

eval {exec gawk -v newtable=$arg -f ../formsql.awk $filename > $as400}

Thanks for any insight,
Dave
