Question

我正在尝试使用g77编译三个文件。其中一个文件是主文件的子例程，返回

Jades-MacBook-Pro:Jade jadecheclair$ g77 -c atmsetup.for 
Line too long as of (?) [info -f g77 M LEX]

我对fortran很新，在网上找不到任何解释。另外两个文件工作并创建.o文件，其中一个（也是一个子例程）看起来与此文件完全相同。

任何人都知道这意味着什么以及如何解决它？

由于它不让我知道哪条线路造成了麻烦，我在这里附上代码：

      SUBROUTINE ATMSETUP(NLEVEL,Z,RHCH4,FH2,FARGON,TEMP,PRESS,DEN,XMU,
     & CH4,H2,XN2,AR,IPRINT)
C THIS IS THE NEW ONE WITH THE BWC EQ OF STATE
      PARAMETER (NMAX=201)
C THIS SUBROUTINE SETS UP THE INTITAL ATMOSPHERIC PROFILE FOR TITAN
C BASED ON THE LINDAL ET AL DATA.  THE ROUTINE STARTS WITH INPUTS
C INPUTS:  
C NLEVEL:   NUMBER OF ALTITUDE LEVELS, J=1 IS AT THE TOP
C Z         ALTITUDE GRID IN KM
C RHCH4     RELATIVE HUMIDITY OF METHANE AT Z=0.
C FH2       MIXING RATIO BY NUMBER OF H2
C FARGON    ARGON FLAG 0 = NO ARGON IN ATMSOPHERE 
C                     -Y = ADJUST AR TO GIVE MEAN WEIGHT=Y
C                     +X = MIXING RATIO OF ARGON = X
C OUTPUTS: AT EACH LEVEL (NOT LAYER AVERAGES)
C TEMP (K), PRESS(BARS), DEN(CM-3), XMU = MEAN MOLECUALR WEIGHT
C CH4, H2, XN2, AR ARE THE NUMBER MIXING RATIOS OF THE GASES
C INTERNAL VARIABLES
C TLINAL, DLINAL, PLINAL : THE LINDAL INGRESS VALUES ON THE Z GRID
C
C NOTES: METHANE FOLLOWS CONSTANT MIXING RATIO UNLESS SATUARTION
C        VALUE IS LOWER.

Answer 1

我将您的代码复制并粘贴到文本编辑器中并查看它。你的第二行，第1行的SUBROUTINE语句的延续似乎在错误的列中延续了它的行继续。它应该是第6列。

Answer 2

通过在vim中打开文件可以看到问题。即使程序在Xcode中看起来很好，所有的线都在一起。

刚刚在textedit中打开文件并重新格式化。然后它奏效了！
