There is a regression in FTN95 5.20 which causes some ALLOCATE statements to fail. You can download a fixed compiler here: http://www.ftn95.co.uk/ftn95/ftn95_5_20_1.zip. The archive contains one file, ftn95.exe, which should be copied over your existing FTN95 5.20 executable (which by default on 32-bit systems is in directory C:\Program Files\Silverfrost\FTN95).
Thank you to Kenny Tilley for reporting this problem.
