I am just beginning to port some programs from FTN77 to FTN95 and have come across a problem. The following example is similar to the one given on p162 of the User's Guide.

CHARACTER FLTNO*6,AIRLN*2
INTEGER*4 LA
FLTNO = 'BA 748'
LA = 2
AIRLN = FLTNO(1:LA)
END

With FTN77 this compiles and runs without a problem, assigning the value BA to AIRLN. With FTN95 it compiles but a run-time error occurs at the AIRLN = ... line, with the following message ...

Error 29: Call to missing routine : _CHECK_S_BOUND# at 0x00401059

Can someone please explain what is happening here?

Sedgley

Please provide the FTN95 version number and the FTN95 command line arguments that you are using.

[Sedgley]

The FTN95 version number is 8.80.0
Command line arguments /CHECK /UNDEF

[PaulLaidler]

Your program works OK for me so please try v8.84 available for download from http://forums.silverfrost.com/viewtopic.php?t=4245.

[Sedgley]

Thanks.
I've download v8.84 but using it gives the same run-time error.

[PaulLaidler]

My apologies. The missing routine will be in the updated salflibc.dll which you can download from the same place.

[Sedgley]

Great. That's solved it.
Thank you

I am puzzled, as I am using version 8.80.0 but can not reproduce the problem.

I also tried the following, to see if the unused AIRLN might have been removed, but both options work ok

The reference to the RTL routine CHECK_S_BOUNDS is generated by the compiler when options such as /undef are used. The routine itself is in one of the Silverfrost DLLs.

For a given compiler version such as 8.80, several different versions of the DLLs may have been released on different dates, and we do not know which DLL versions were used for the original post.

Thanks to everyone for the help. I discovered that there was an old version of SALFLIBC.DLL in the system path. Correcting this has solved the problem.
Mea Culpa.
