Some pages from the first Fortran manual, the IBM manual for the 704, are shown. First, for those who think that Fortran was originally spelled with all capitals, there is the cover page [Note: all caps are used frequently inside the manual, often with all but the first "F" in small caps.] Next, is the title page,

This handout should serve you only as a reference to the commands of Fortran in the ANSI 77, 90 and 95 standards. Only rudimentary examples are given to remind you of the syntax, and some tedious details that you are not expected to remember are tabulated for reference purposes.

One of the attractions of Fortran77 is that a good free compiler exists in the form of GNU Fortran, g77. At present I don't know of any free compilers for full Fortran95, but you can download a compiler for a subset language called F, which seems an excellent way to learn modern Fortran.

Extension in Fortran 90 regarding the FORMAT-letters ... IMPLICIT - default IMPLICIT REAL(A-H, O-Z), INTEGER(I-N) IMPLICIT NONE - not standard, but very useful, it is available in Fortran 90. Gives the "Pascal convention" that all variables have to be specified.
