programming language is a formal language that specifies a set of instructions that can be used to produce various kinds of output. Programming languages generally consist of instructions for a computer. Programming languages can be used to create programs that implement specific algorithms.

It's a general tag that covers the topics related to programming with InterSystems Data Platform using different languages.

Question Joel Solon · Feb 18, 2016

This morning on the old Caché Google Group, someone posed the following question, which I've decided to answer here, because it's interesting!

Is there a way to iterate ClassMethod's params, and get param's names and values?

The first answer I can come up with is: it's not easy! In any method, you could try to write code like this (where methodName is the name of your method):

    set method = ##class(%Dictionary.MethodDefinition).IDKEYOpen($classname(), methodName)
    set args = method.

XData blocks in Caché classes has a MimeType property, and dcoumentation says

MimeType — The MIME type (more formally, the internet media type) of the contents of the XData block. The default is text/xml

But unfortunately I can't set any other values, such as text/html or application/javascript, because XData still expect only XML. 

So, question is, for what reasons this property was appeared?

It would be very usefull to set in this property anything other then text/xml, and Studio would highlighted it as developer expected.

Hi

Totally new to IRIS and Cache.

Trying to evaluate it and work out how we could use it.

As a standard application database. Object or relational etc. does not matter. 

Issue is ObjectScript.

So:

1) Can we develop, maintain and use an IRIS database and never use ObjectScript i.e. use only Java, Python, C++ interfaces etc. (exactly which one does not matter)? Would that make designing and using the IRIS database more prone to inefficiency and error?

2) Can we import an existing Cache database into IRIS and convert its ObjectScript code into Java, Python whatever?

Question Marc Mundt · Aug 9, 2016

A new Health Connect customer has a few experienced Java folks on their interface team. As they get more into Health Connect and learn Caché ObjectScript they thought it would be useful to have a list of common Java statements with an equivalent statement in ObjectScript. They mentioned string manipulation as an example, but would be interested in other areas as well.
 
This seems like something that is probably already floating around somewhere. Does anyone have something like this or other "COS jumpstart for Java devs" materials?
Thanks,
Marc

Question Scott Beeson · Feb 8, 2016

I've searched the ObjectScript reference for any instances of Upper, Lower or Case and the only thing is a case/switch statement.  In all the documentation I can only find SQL and Cache Basic references for things like UCASE.

So how do I do this in ObjectScript?

For instance,  if (ucase(dtype)="G") { }

Question Sehinde Raji · May 21, 2021

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 ?
