I am a newbie who is trying to learn how to set up a basic connection to Iris using a node js application. I am astounded at the lack of documentation there is on how to do this and even more concerning there are a few errors within the documentation. For example I am on the Native API application within the below link.

https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cl…

And it says that you need to create a directory the thing is that it doesn't state which directory this needs to be or any other history.

I am currently running a docker image with Iris 2021.1 and I would like to install node js on to it. I have had a look at the instructions on the intersystems online learning portal and I must say its very confusing. Some of the documentation says that you can only install it on 2019. Other parts say that it doesn't matter and you can install it if you have a dev directory. I checked my dev directory and there it isn't there. Sadly this is very inconsistent. Does anyone know if it is possible to install on the above mentioned version of Iris ?

Hey everyone as you may know I am a beginner and I am kindly asking for some assistance in a problem I have been solving. The problem is that I am calling a user defined function within a procedure called occupiedseatsAdj and the compiler comes up with this error. 

From what I understand I can call a user defined function from within a procedure (correct me if I am wrong) as shown below. Is this the correct way or should I create a .Mac file and include it somewhere within the above mentioned cls file ?

Hi All I am a beginner and I am learning Objectscript and I would appreciate a steer regarding a problem I am solving.

The issue I have spent some time on resolving without success is that I have the stream listed below and as you can see it has some gaps in it.

Stream

das
is
wp

dsa
nmk

Here is the import method

IF ##class(%File).Exists(dir) '=1 {
    write !, "Unable to Open: "_dir
    QUIT
} ELSE {
    write "File: "_dir_" is open"
}
// instantiate a new class called file
set file = ##class(%Stream.FileCharacter).%New()
// create a new variable called sc
set sc = file.

I have been working within Objectscript for a few months and I am seeking assistance today because all of the help files within the docs.intersystems.com domain are currently down and they wont be back up until next week. (I raised a special ticket for this) 

I have been trying to figure out how to  convert a binary number 0101001 in to a decimal number using a variable called CNumber and I have tried using the method below and it hasnt worked. I think it may be due to the fact that this assumes an array or some sort.

Hi all, I am new to IS Objectscript and I would appreciate some assistance regarding this.

Hey I am very new to Intersystems Objectscript and I am trying to find a way of extract 4 digit numbers from a stream.

I have a stream full of results 

2334

3434

5543

4334

And I am trying to remove each 4 digit grouping from the stream.

I have tried the following for loop 

for i=1:1:$length(result) {

set curr = $extract(result, i)

write !, curr

set count(curr) = $get(count(curr)) + 1

}

Unfortunately the loop extracts one digit.

Does anyone have any suggestions on how to solve this ?
