Please be aware that (in the UK at least) automatic updates for Windows 11 now give you version 24H2.

Win32 applications that contain calculations that underflow will currently not recover unless underflows are masked.

This only applies to Win32 applications, not x64 and not .NET.

Win32 underflows can be masked by either:

a) calling mask_underflows@() or
b) setting the environment variable SALFENVAR=mask_underflows

This applies for all versions of salflibc.dll prior to FTN95 v9.10.
