I am writing a c++ program that has many calls of pow(input,2). I now realize that this is slowing down the program and these all should be input * input for greater speed.
There should be a simple way of doing this replacement throughout my file with awk, but I am not very familiar with awk.... (2 Replies)

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"
}
