#ObjectScript

InterSystems ObjectScript is a scripting language to operate with data using any data model of InterSystems Data Platform (Objects, Relational, Key-Value, Document, Globals) and to develop business logic for serverside applications on InterSystems Data Platform.

Documentation.

I am still new to cache objectscript and am trying to figure out how I would go about removing the escape characters from my JSON below. When I call the $toJSON method it's adding the "\" character in the file path.

{"FileStatus":"P","Path":"\/somepath\/test\/test123\/filename.txt","InterchangeOID":"100458"}

My Code:

When is a number not a number?

Noticed some unexpected behavior when using $ZTH

Resultant values less than 1 are treated as strings and values >=1 are numbers. Causing heartburn in $Query / $Next / $Order loops. Is there a setting somewhere that can change this?

Example:

// Parse the time out of a text string whose format is YYYYMMDDHHMMSSsssssssss (lower case s = fractional parts)

Set MsgDT = "20180405000000001005933"
Set MsgDTH = $ZTH(($E(MsgDT,9,10)_":"_$E(MsgDT,11,12)_":"_$E(MsgDT,13,14)_"."_$E(MsgDT,15,23)),1)

//Do it again, but add a sec to the time string

Hello,

Is it possible to write global output values to STDOUT, in a similar way to how csession can take routine intput, like below:

(In Cache Terminal)

%SYS>d ##class(%SYSTEM.License).ShowSummary()

License Server summary view of active key.

Distributed license use:

Current License Units Used = 1

Maximum License Units Used = 1

License Units Authorized = 200

Local license use:

Current Connections = 1 Maximum Connections = 1

Hi all

Does anyone have an easy way of reading the cdata in the xml response returned buy a Webservice?

At the moment I have a XML class and then I use read.Correlate() to read through that XML bit.

However, depending on the message I have different things in the CData and I don't want to create a class for each one of these.

The API returns the cddata as KeyValueOfstringstring.

anyone know of a simple way to search a blob of text from a list of keywords in one fell swoop, without having to iterate through each keyword and perform an individual search? Ex.

s keywords="This,blob,text"

s text = "This is a sample blob of text"

i text[keywords w "hit"

Hello All

I'm running into an issue performing UPDATES that I'm not getting on INSERTS. It's probably obvious, but I'm just not seeing it and could use a little help.

I'm going over an HL7 message and depending upon varying criteria, the relevent variables will get items added to them like the following:

Set patientId = pRequest.GetValueAt("PID:3")
Set sqlColumns = sqlColumns_",patient_id"
Set sqlValues = sqlValues_",?"
Set par($i(p)) = patientId

After compiling the variables, I check to see if accession number is found in the table.

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.

I am receiving the following error in my buisness operation:

ERROR <Ens>ErrException: <UNDEFINED>zGo2+181^mb.MbMainOperation.1 *tSC -- - registered as '-' number - @' set pResponse = ##class(mb.MbMessageResponse).%New()'

From what I understand, the problem occurs in the generated int file mb.MbMainOperation.1 in the method zGo2, with the offset of 181 lines, and the variable in question is a local variable tSC.

However, the line where the error occurs does not refer to tSC in any way

Was wondering if anyone had a simple way of calling ##class(Ens.Director).EnableConfigItem() within a Business Process or adding code to a Custom Service to start or stop the object?

The use case is that I have a Process that uploads a file into a external SQL table. When it is finished I want it to kick off another Service that does the processing of the data that it just uploaded. Once it is finished the response is sent back to the service and when the service receives the response from the process, I want to stop that service from running.

so...

I am currently debugging a piece of code relying heavily on macros. I am using breaks in the method to then check the values of macros and object properties as I go. However, any time I invoke a macro within a break I get an error. To get around this I am converting the macro calls into the underlying code. Some of these macros have messy translations and this is somewhat time consuming. Is there an easier way to access macros from within a break?

In VS Code using the InterSystems ObjectScript extensions, I'd like the indentation applied to match that of IRIS Studio. Specifically for comments and dot syntax, I'd like pressing enter (carriage return) to preserve the current dot depth and same comment beginning.

In IRIS Studio after changing the indentation settings to custom using " \t.#/;" without quotes (note the leading space), the behaviour looks like this:

Load a dll at run time

I am using java gateway imported/proxy classes and JG business service. I need to load a dll at run time.

I use System.loadLibrary/System.load when in java. I’ve tried $ZF(-3,” C:\Windows\System32\pteidlibj.dll”) and $ZF(-4,1,"C:\Windows\System32\pteidlibj.dll") but I’m getting <DYNAMIC LIBRARY LOAD> error.

How can I load a dll at run time using COS?

Hi!

Here is the question in Russian Forum regarding roots extracting.

In Caché ObjectScript we use exponentiation operator (**) to raise an exponent to power. F.e. let's raise 3 to power of 3: 

USER> write 3**3 

27

And we use the same operator to extract the root. 

USER> write 27**(1/3) 

2.999999999999999963

And 2.999999999999999963 is not 3, obviously.

How to extract roots properly in Caché ObjectScript?
