Hello all

I am repeatedly getting Line 1: Parse error when I try to execute my udf in interpreted mode.

Is anybody having any idea about it?

How can I get rid off?

Regards Karthick

post your udf !

This is my udf. I am trying to add the velocity values of each cell with values given in the datafilenew.dat file

#include "udf.h" DEFINE_ADJUST(my_adjust,d) {

Thread *t;

cell_t c;

FILE *fp=NULL;

real uturb=0.;

float arr[500];

int i=0;

fp=fopen("datafilenew.dat","r");

while (!feof(fp))

{

fscanf(fp,"%f",&arr[i]);

i++;

}

fclose(fp);

i=0;

thread_loop_c(t,d)

{

begin_c_loop(c,t)

{

C_U(c,t)=C_U(c,t)+arr[i];

i++;

}

end_c_loop(c,t)

} } Regards Karthick

I am not an very experinced in these funcitons, but I almost always find a Parse error is due to a forgotten ; somewhere, although I coudn't see any in your UDF. Is there a problem with this line?

while (!feof(fp))

What is it's funcitons. Should a while not contain a conditioal statement, like < or ==?

Sorry I coudn't be more help.

Another thought? do you need this header file at the top of your UDF to access the file functions?

#include "fstream.h"

Hello

I've tried the udf after including fstream.h file. But again the error is coming. Also while(!feof(fp)) is correct i.e., the loop will go into the file till the eof is reached(end of file).

The thing is I am having a dat file which contains some numbers. I have to take each number and store it in a array till eof is reached. Is anyothe way of doing it?

Sure the path of your udf file is right. I suggest you use full path.
