The AOCC flang compiler fails to parse valid Fortran code when the `FORMAT` keyword is written in uppercase, throwing a misleading error about "illegal hexadecimal constant". The identical code compiles successfully when using lowercase `format`.
System Information
- CPU: AMD EPYC 7003 series
- OS: Ubuntu 24.04
- Compiler: AOCC%5.0.0 flang
- Reproduction: 100% reproducible
Minimal Reproduction Code
```fortran
! test.f
program minimal_test
write(*, 100)
100 FORMAT(1X 'TEST')
end program minimal_test
![]()
