String of Variable Length

[GerritGroot]

Hi,

Maybe a stupid question, but if I want to specifiy a string of a variable length, without it being an argument of a subroutine, what do I do?

CHARACTER*(*) :: ch

Is not allowed, because it's not an argument to a routine
(Never understood the extra (*) BTW)

CHARACTER, DIMENSION), ALLOCATABLE :: ch

Is an option, but that's an array of characters and not a string.

Is there a more elegant solution?
Any suggestions?

Thanks,

Gerrit

No intrinsic varying length strings in Fortran, but see:

Okay, thanks, I'll have a look.
