twirly thing

(OP)
I'm a new user of gfortran and am wondering how you implement
a non-advancing write.

The following code fragment works fine under IVF.

CLOSE(UNIT=6)
OPEN(UNIT=6, CARRIAGECONTROL='FORTRAN')
DO I = 1, 1000
WRITE(6, 10) '/'
WRITE(6, 10) '-'
WRITE(6, 10) '\'
ENDDO
10 FORMAT('+',2A)
CLOSE(UNIT=6)
OPEN(UNIT=6, CARRIAGECONTROL='LIST')

Thank you.

RE: twirly thing

Try something like this

CODE

program main
   character(len=1):: bksp
   
   bksp = char(8)
   do ii = 1, 2000
      write(*, 10, advance='no') '/', bksp
      write(*, 10, advance='no') '-', bksp
      write(*, 10, advance='no') '\', bksp
      write(*, 10, advance='no') '|', bksp
   10 format(2A)
   end do
end program main 
This loop finishes in no time so you might want to think of some sort of delay in between the writes

Backspace, Duh!!!

Working now thank you.

White Paper - How ESI is Helping Move New Medical Device Product to Market Quicker & More Cost Effic
Early Supplier Involvement has long been a strategy employed by manufacturers to produce innovative products. Now, it almost seems like a necessity. Because decisions made in the design phase can positively affect product quality and costs, this can help add value to OEM bottom lines. This white paper will discuss many facets of ESI, including why it’s so valuable today, what challenges limit the benefits of ESI, how cost is impacted, and more. Download Now
White Paper - Moving to a Driverless Future
This white paper describes what we see as the best practices to support a sustainable engineering process for autonomous vehicle design. It exposes how to use simulation and testing in common frameworks to enable design exploration, verification and validation for the development of autonomous cars at a system, software and full-vehicle level to drive a mature product development process for automated driving.

Research Report - How Engineers are Using Remote Access
Remote access enables engineers to work from anywhere provided they have an internet connection. We surveyed our audience of engineers, designers and product managers to learn how they use remote access within their organizations. We wanted to know which industries have adopted remote access, which software they are using, and what features matter most. Download Now
