Yes, it works in interactive mode :

MacBookJB:Downloads marquett$ wcstran lm04510_newwcs.fits  framein=pixel frameout=sky
POSIN - Position to be transformed /'500,500'/ > 500,500

  p1 = 500.0  p2 = 500.0  -->  RA = 5:19:58.0  Dec = -65:07:18

My point is that I will have 15 Tb of images to autoastrom to get the QV keywords, and then to rebuild a catalogue of 87 million objects using wcstran, so I do need the command-line mode. Also, how to modify the number of digits on seconds on the output to get ss.ss on RA and ss.s on DEC ?

Anyway, thanks for your help,
