Your code snippet certainly will not do what you expect it to do. A for loop doesn't read from stdin, so a redirection from filelist.del won't do anything (unless the loadutility will read from there). The loop itself will iterate exactly once with the $i variable assuming the value FIELD1.FIELD2.FIELD3.FIELD4.index, and the $j assuming FIELD1.FIELD2.FIELD3.FIELD4. The loadutility command will execute with the "FIELDn" string constants exactly as written; expansion will be performed on the $j variable only.
"I might have to throw some awk into the equation" - on what? Where? What is your target? What is your input? What is your OS, and shell? And, do you want to "parse a file name", or a file ('s contents)?

continue
continue(3tcl) Tcl Built-In Commands continue(3tcl)
__________________________________________________________________________________________________________________________________________________
NAME
continue - Skip to the next iteration of a loop
SYNOPSIS
continue
_________________________________________________________________
DESCRIPTION
This command is typically invoked inside the body of a looping command such as for or foreach or while. It returns a TCL_CONTINUE code,
which causes a continue exception to occur. The exception causes the current script to be aborted out to the innermost containing loop
command, which then continues with the next iteration of the loop. Catch exceptions are also handled in a few other situations, such as
the catch command and the outermost scripts of procedure bodies.
EXAMPLE
Print a line for each of the integers from 0 to 10 except 5:
for {set x 0} {$x<10} {incr x} {
if {$x == 5} {
continue
}
puts "x is $x"
}
