FORTRAN 66 - Example Program Code

This section provides a simple example program code of FORTRAN 66 language.

Here is a simple example code of FORTRAN 66 (FORTRAN IV) for an IBM1130 using 8Kb memory in 1973 (Source: www.thocp.net):

// JOB
// FOR
* ONE WORD INTEGERS
* IOCS(DISK,TYPEWRITER,KEYBOARD,PAPERTAPE)
      DIMENSION IEMG(10,15),IEMG1(13)
      DEFINE FILE 12(80,150,U,K)
      WRITE(1,10)
   10 FORMAT('PAPERTAPE'//'GIVE NUMBER EXPERIMENT (1-5 IN INT)')
      READ(6,30) M
   30 FORMAT(I1)
      PAUSE 1
      DO 25 N=1,16
      DO 15 I=1,15
      READ(4,20) IEMG1
   20 FORMAT(13I4)
      DO 15 J=4,13
      J3=J-3
   15 IEMG(J3,I)=IEMG1(J)
      NE=N+(M-1)*16
   25 WRITE(12'NE) IEMG
      CALL EXIT
      END
// DUP
*DELETE SJA1
*STORECI WS UA SJA1
*FILES(12,EMG)

Note that JCL (Job Control Language) commands were used to control how the FORTRAN should be executed in the above example.
