  •  Hi Andrew,

                     Sorry for not informing about the error properly.

    I did the modification you mentioned. Now the error is not there but an infinite loop is running resulting some junk data. My entire code is:

    list_so_far=list()
    var1=var2=0
    PortDef=infile("~/file.txt")
    when(PortDef
        while(fscanf(PortDef "\n%d %d\n" var1 var2)
            list_so_far=append1(list_so_far var1)
            list_so_far=append1(list_so_far var2)
        );while
    close(PortDef)
    );when

     

    The file.txt contains lines like-

    p 1 4

    23 34

    43 65

    765 9

    0 345

     

    p 1 4

    213 354

    43 685

    765 95

    70 345

     

    I am interested in [213 354] like lines only not [p 1 4] ie the lines starting and ending with integer only.

    Please assist.
