Full Discussion: Awk Script Counting of Correct vs. Error Responses
Top Forums Shell Programming and Scripting Awk Script Counting of Correct vs. Error Responses Post 302500414 by alister on Monday 28th of February 2011 02:07:39 PM

From a quick peek at your code, it looks like the block of if statements is executing on every single line that's read. And, since they test for every possible combination of arrow and choice, a counter will increment on each line read.

Perhaps something along these lines will work (untested).
Code:

igawk ' 

BEGIN{

   OFS=" "
   arrow = ""
   response = ""
   correct = 0
   error = 0
   totalpoints = 0
}


####################### Patterns #############################


#note:  search string may have trouble with newlines as ^M?
/^Arrow:/ { arrow = $2 }
/^Choice:/ {
    response = $2 }
    
    #  Compare arrow to response, increment the appropriate counter, and reset
    if (arrow == "<--" && response == "left") || (arrow == "-->" && response == "right")
        correct++
    else
        error++
    arrow = response = ""
}

END{
    print "correctChoices = " correct, "incorrectChoices = " error;
}

' $*

This solution is essentially the same as yinyuemi's minus the gsubs (sorry, missed that before I started).

mms_rsp_type

mms_rsp_type(3MMS)				     Media Management System Library Functions					mms_rsp_type(3MMS)

NAME

       mms_rsp_type, mms_get_tree, mms_get_str, mms_get_attribute, mms_handle_err_rsp - MMS client functions for handling responses

SYNOPSIS

       cc [ flag...] file... -lmms [ library...]
       #include <mms_api.h>

       int mms_rsp_type(void *response);

       mms_par_node_t *mms_get_tree(void *response);

       char *mms_get_str(void *response);

       char *mms_get_attribute(void *response, char *name, void **prev);

       int mms_handle_err_response(void *response, int * class, int * code,
	    char **message);

DESCRIPTION

       For these functions, response is the MMS response to an MMP command sent by the client.

       The mms_rsp_type() macro returns the type of the response. The following is a list of responses:

       MMS_API_RSP_UNACC	 unacceptable response

       MMS_API_RSP_FINAL	 success response

       MMS_API_RSP_FINAL_INTR	 intermediate response

       MMS_API_RSP_FINAL_ERR	 error response

       MMS_API_RSP_FINAL_CANC	 cancelled response

       The mms_get_tree() macro returns the parse tree of the response.

       The mms_get_str() macro returns the response string.

       The  mms_get_attribute()  function takes a response with name values looking for name, and returning the value associated with it. A client
       can call this function multiple times if the response contains multiple instances of name. When all occurrences of name	have  been  found,
       NULL is returned.

       The  mms_handle_err_rsp()  function  processes  an  error response on behalf of the client. It returns the error class, error code, and the
       internationalized error message if one was included.

RETURN VALUES

       Upon successful completion, mms_handle_err_rsp() returns MMS_API_OK. If it encounters a processing error, it returns an error code indicat-
       ing the type of error.

ERRORS

       These functions will fail if:

       MMS_API_ERROR	      Unable to obtain error class or code.

       MMS_API_NOT_ERR_RSP    Response is not an error response.
