eof文件尾函數不適用的緣故，參照文末fortran讀文件時判斷文件結束的兩種方法

1. 修改reorder.f90

do while (.true.) n=n+1 read(fino,*,iostat=stat) (a(i),i=1,opno) if(stat <= 0) goto 100 end do 100 no=n

出錯結果no=0

修改爲：

do while (.true.) n=n+1 read(fino,*,end=100) (a(i),i=1,opno) end do 100 no=n

結果爲：

*******reorder the edges******* nted 173 At line 95 of file reorder.f90 (unit = 60, file = 'cubic.tedfulledge') Fortran runtime error: End of file

nted爲173大於172，讀下一個文件的時候超過文件行數

修改爲no=n-1，結果爲：

*******reorder the edges******* nted 172 nsrcedge= 0 nbdedge= 156 total free edge= 156 *******test ted edge******* Nted 172 Nedge 288 173 173 289 289 段錯誤

 

段錯誤定位於testtededg.f90中Line 69循環當中。

 

用原Translate_code，做類似本文修改，沒有出現錯誤。執行結果爲：

2. 修改testtededg.f90

do while(.not.eof(300)) ip1=ip1+1 read(300,*) (tededg(i,ip1), i=1,6) end do ip2=0 do while(.not.eof(400)) ip2=ip2+1 read(400,*) (tedfull(i,ip2), i=1,6) end do ip3=0 do while(.not.eof(500)) ip3=ip3+1 read(500,*) (testedg(i,ip3), i=1,2) ! .edge file end do ip4=0 do while(.not.eof(600)) ip4=ip4+1 read(600,*) (full(i,ip4), i=1,2) ! .fulledge file end do close(300);close(400);close(500);close(600)

改爲

 

do while(.true.) ip1=ip1+1 read(300,*,end=10) (tededg(i,ip1), i=1,6) end do 10 ip2=0 do while(.true.) ip2=ip2+1 read(400,*,end=20) (tedfull(i,ip2), i=1,6) end do 20 ip3=0 do while(.true.) ip3=ip3+1 read(500,*,end=30) (testedg(i,ip3), i=1,2) ! .edge file end do 30 ip4=0 do while(.true.) ip4=ip4+1 read(600,*,end=40) (full(i,ip4), i=1,2) ! .fulledge file end do 40 close(300);close(400);close(500);close(600)
