在awk中，搜索当前行的某些特定列

我有一个名为的文件c_FROM_V_273_008245_50_neighbours_SYMREMO.out，看起来像：

NEIGHBORS OF THE NON-EQUIVALENT ATOMS

N = NUMBER OF NEIGHBORS AT DISTANCE R
ATOM  N     R/ANG      R/AU   NEIGHBORS (ATOM LABELS AND CELL INDICES)
1 CA   1     2.4055     4.5458    7 O    0 0 0
1 CA   1     2.4058     4.5463   10 O    0-1 0
1 CA   1     2.4356     4.6026   14 O    0 0 0
.
.
.

如果我想搜索的距离R/ANG的1 CA 7 O，这将是2.4055

我创建了以下脚本：search_for_distance.awk：

 {if ($0 ~ "NEIGHBORS OF THE NON-EQUIVALENT ATOMS") {FLAG=1}};
 # If the current line of the file begins with that string, we asign it a FLAG=1

    {if (FLAG==1)
            {if ($0 ~ "^   1 CA"){LINE=$0;
            exit}
            }
    };
    # Here I am searching for "1 CA" on each line

 END{VOL=FILENAME;
 # The filename is: "c_FROM_V_273_008245_50_neighbours_SYMREMO.out"
 # My intention is to end up with a new file with 2 columns:
 # "volume" and "distance". 
 # Notice that the filename contains the volume: 273.008245

 gsub("^.*_V_","",VOL);
 gsub("_",".",VOL);
 gsub(".50.neighbours.SYMREMO.out"," ",VOL);
 # Some substitutions to make "c_FROM_V_273_008245_50_neighbours_SYMREMO.out" 
 # to be "273.008245"

 # Up to now the output of running: 
 # search_for_distance.awk -f c_FROM_V_273_008245_50_neighbours_SYMREMO.out
 # is the following:

 # 273.008245     1 CA   1     2.4055     4.5458    7 O    0 0 0

 # So, I need to take LINE and only extract column "4".
 # This is done by a "split" command:

 {split(LINE,array," ")}   

 print VOL,array[4]}

running：的输出search_for_distance.awk -f c_FROM_V_273_008245_50_neighbours_SYMREMO.out如下：

 273.008245  2.4055

请注意，脚本正在打印的1st外观1 CA，恰好是1 CA 7O，这是我想要的。

但是现在我需要运行它以搜索许多距离的首次出现...

我想搜索该1 CA 14 O距离的首次出现。我只需要将我从行首搜索到的代码的第一位修改为1 CA：

 {if ($0 ~ "NEIGHBORS OF THE NON-EQUIVALENT ATOMS") {FLAG=1}};
 # If the current line begins with that string, we asign it a FLAG=1

    {if (FLAG==1)
            {if ($0 ~ "^   1 CA"){LINE=$0;
            exit}
            }
    };

我该如何介绍要搜索的订单1 CA 14 O？

就像是

    {if (FLAG==1)
            {if ($0 ~ "/1 CA   && /14 O"){LINE=$0;
            exit}
            }
    };

非常感谢您的帮助
