Other printable characters
Printable characters include the tab character (09 hex), ASCII characters with codes in the range 20(hex) through 7E(hex), and characters in certain special character sets.
Printable characters that are not in the Standard Fortran character set can only appear in comments, character constants, Hollerith constants, character string edit descriptors, and input/output records.
Uppercase and lowercase letters are treated as equivalent when used to specify program behavior (except in character constants and Hollerith constants).
