There are several ways.

You could employ the CLI$ routines and your own command definition (.CLD).

... or...

You could place the value in a DCL symbol and then, in your program, call 
LIB$GET_SYMBOL.

... or...

You could also use LIB$GET_FOREIGN or LIB$GET_INPUT to obtain a value for
use in your program.

... or...

Not knowing your Fortran program, you could also use a Fortran READ.  If
it's in a DCL procedure, $ DEFINE/USER SYS$INPUT SYS$COMMAND just before 
you run your Fortran program.
