In GNU Fortran, a symbolic name is at least one character long, and has no arbitrary upper limit on length. However, names of entities requiring external linkage (such as external functions, external subroutines, and `COMMON' areas) might be restricted to some arbitrary length by the system. Such a restriction is no more constrained than that of one through six characters. Underscores (`_') are accepted in symbol names after the first character (which must be a letter). automatically generated by info2www version 1.2.2.9 |
