I want to develop a visual basic program to reading file above.
This is condition i want:
-when vb read '#' character , just skip the line.(line or word begin with '#' is comment)
-when vb read 'D' , split the '1-2' to station value(String), 9997.930 and 0.038 to double(9997.93 to distance value and 0 0.038 to error value for distance)
-above step are same when vb read 'A','B' and 'c'(44-59-19(44 degree 59 minute 19 second),1-2-3 (this is station will convert to string)
-for C, if the line C end with ! ! , i want difference it with another value of c.(!! mean fixed coordinate)

i have try to build this code before , but the code i build are very complex!
I want your opinion how to develop this code.
Thank You for who can help me

1. Use line input function to read the file line by line into a string

2. Use left function to check the first character from the string whether it is # or A or B etc.

3. Use split function to split the remaining string after D or whatever into an array using space as delimeter.

4. To check whether C ends with ! use right function.

I hope this solves your issue. I cannot give you pseudo code at the moment.

Just write a line parser.

i think my code i write before are same concept with what suggest by mbshinde78 , but the problem is the '#' sometime not start at first line , like C 1-2 10000 10000 !! #this is fixed coordinate , how to solve it ?

again l lost the code i write before because my computer have critical problem , i don't save a copy. But i will post my code again when i have finish the code. Thank for your concern.
