EOLN

[Juno]

Hello

Has anyone had any experience with the EOLN command? I have a tab delimited text file and EOLN appears to view the tabs as carriage returns. Is there a different delimiter I am supposed to use?

Thanks,

If you can be sure that each line contains the same number of fields, you can just do:

ReadLn(fieldOne, fieldTwo, fieldThree);

and all three variables will get assigned in one shot. Note that PASCAL requires that each field be non-nil for this to work. So if the data actually look like this:

something-tab-tab-something

you'll have problems. One way to solve this problem, if you're writing the file, is simply to make sure that you don't write any non-nil fields (come up with something that to you denotes an empty field, and write that instead of a nil string).

In situations where the number of fields can vary, I usually just use StdReadLn, which reads the whole line into one variable. Then I parse the variable, looking for the delimiters myself. It's a pain, but it's reliable.

Unfortunately, the lines can have a variable number of entries. The StdReadLn is a possible solution but you are right, it is a pain.

EOLN seemed like a simple answer but it doesn't work the way I expected it to, unlike EOF.

Thanks for the suggestions,
