FORTRAN-80 FORTRAN Concepts

Character data is a string of any characters representable in the processor. The blank character is valid and significant in a character constant. A character constant has the form of a string of characters surrounded by apostrophes. An apostrophe within the string is represented by a double apostrophe. A character constant can have 1-255 characters.

For the sake of compatibility with earlier versions of FORTRAN, FORTRAN-80 also supports Hollerith type data under the guise of arithmetic/logical types. The Hollerith type is summarized in Appendix C.
