CHARACTER; scalar; INTENT(IN).
Intrinsic groups: (standard FORTRAN 77).
Returns the code for the character in the first character position of C.
Because the system's native character set is used, the correspondence between character and their codes is not necessarily the same between GNU Fortran implementations.
Note that no intrinsic exists to convert a printable
character string to a numerical value.
For example, there is no intrinsic that, given
'154', returns an
REAL value with the value
Instead, you can use internal-file I/O to do this kind of conversion. For example:
INTEGER VALUE CHARACTER*10 STRING STRING = '154' READ (STRING, '(I10)'), VALUE PRINT *, VALUE END
The above program, when run, prints:

See IAChar Intrinsic, for the function corresponding to the ASCII character set.
