WRITEPRN inside a conditional clause

[MazAwushu]

Hello,

How can I write a text file with a matrix only when a condition is true?
The problem I encountered is that you cannot use the := assignment inside an if-clause. Instead you've got the <-- (arrow - local assignment), which is unfortunately not working with WRITEPRN.

To sum up, I would like to do sth like this:
if(a, (WRITEPRN(filename) <-- data), 0)

I will accept any working solution. Even not using this very pattern.

Thank you in advance,

Try

if(a, WRITEPRN(filename, data), 0)

Thank you very much for all your responses, it helped me a lot.

However, this works only when WRITEPRN is the returned value.
In my case the above conditional is part of a function.

For ex:

mywrite(filename, data) = | //do-something-before-write
| WRITEPRN(filename, data)
| return 1

the above does not work, but it does without the "return 1" line.

So my last question is: can we, anyhow, return something else then just the WRITEPRN function result?

Thank you once again for all your replies.

I don't seem to have a problem with using "return 1"

However, if the problem is the fact that mywrite returns an array, then try returning "rows(WRITEPRN)"

Why can't you just assign it to a function?
