I learnt Fortran (back in 2009) by reading Lahey’s Fortran 90 book. ---

My favorite compiler at my first job was Lahey’s. It provided the clearest error messages (at least from the compilers I had access to at the time). Sad that it is officially discontinued. ---

Tom, thanks for all the work and support you and Lahey have given to the entire Fortran community over the years. We’ll miss Lahey, truly a great compiler, a great company, and you are a true gentleman. Thank you. ---

I still have some working version, twenty years old: ```nohighlight lf95 --version Lahey/Fujitsu Fortran 95 Compiler Release L6.10a S/N: LP072812 Copyright (C) 1994-2001 Lahey Computer Systems.

Are they in a position to open source their Fortran compiler if they will not be in the Fortran compiler business anymore? That would be awesome if they could do that. ---

> [@certik](#): > > Are they in a position to open source their Fortran compiler if they will not be in the Fortran compiler business anymore? > > That would be awesome if they could do that Great point @certik. @RonShepard expressed the same thought in a related discussion at comp.lang.fortran with the other one also, Absoft Fortran compiler. Perhaps this can be Google Summer of Code project next year to establish open source repositories for both Absoft and Lahey Fortran compilers if the legwork can be completed now by this Community to reach out to surviving communication channels for Absoft Inc. and Lahey Inc. and influence them to **not** make their great products as abandonware but rather that they can have their outstanding legacy live on as open source efforts!
