I have a problem generating QR code in Caché now.

After executing the code

set Status=##Class(%SYS.QRCode).GenerateImage(P0,,.DataURI)

(variable P0 contains data for QR code)

an error is displayed now:

Iterate over array of namespaces

How do you iterate over the array of namespaces returned in the result byref from the call below?

DO ##class(%SYS.Namespace).ListAll(.result)

Running "zw result" displays the namespaces (as individual subscripts in result) in the Terminal but I want to be able to programmatically iterate through each namespace name.

I'm using a %Net.HttpRequest which had been successful in the past, but started failing at some point with a SSL/TLS protocol error.

ERROR #6085: Unable to write to socket with SSL/TLS configuration 'groundca', error reported 'SSL/TLS error in SSL_connect(), SSL_ERROR_SSL: protocol error, error:14077102:SSL routines:SSL23_GET_SERVER_HELLO:unsupported protocol'

I have an application that is requires an Encoded HL7 message sent over SOAP over HTTPS using SSL/TLS... the Response that is return is also encoded, which I know how to Decode but not sure when I Decode the response how to Extract the HL7 message to send back to the router.

How do I capture the Routing Source System and parse the encoded message back into an HL7 format that would show on the trace viewer?

We have a vendor that is requiring that the HL7 sent to them is sent as an Encoded message inside a SOAP request but is sending back an HL7 message as the response.

When the WSDL built the response, it was expecting an encoded message back. I updated the Request and Business Operation to expect an EnsLib.HL7.Message, however I am not sure how to handle the HL7 ACK to post it back to the sending message so it will not cause an Orphan message, and to parse it back correctly in the trace viewer.

When I do a $$$LOGINFO on the pResponse, I get back...

My intention is to show how simple it is to generate a lookup table taking into account the information received in our HL7 messaging. The HL7 message lookup table provided by IRIS is certainly sufficient for most of the searches we want to perform, but we always have that special field in our HIS, LIS, RIS, etc. that we'd like to search by. But that's in a segment outside of that lookup table. That field forces us to generate a specific search using the expanded search criteria.

Concatenation Issue

I am trying to add a value to my concatenation string and the value is not being inserted in the right place. I am adding onto this code from another developer and cannot seem to get it to work. The only code I have added is underlined in bold red.

This is how the translated HL7 message looks:

OBX|1|CE|CDX^History||Specimen 1 Clinical History: CLINICAL HISTORY\.br\\.br\Specimen 2 Clinical History: CLINICAL HISTORY 2\.br\Specimen 1 Suspected Clinical Diagnosis\.br\Specimen 3 Clinical History: HISTORY 3\.br\Specimen 2 Suspected Clinical Diagnosis

Having been inspired with Shared code execution speed question/discussion, I dare to ask another one which is annoying me and my colleagues for several weeks.

We have a routine called Lib that comprises 200 $$-functions of 1500 code lines total. It was noticed that after calling _any_ function of another rather big routine (1900 functions, 32000 lines) the next call of $$someFunction^Lib(x) is getting 10-20% slower than previous call of the same function. This effect doesn't depend on:

Hey everyone,

I'm diving deeper into Caché ObjectScript and would love to open a discussion around the most useful tips, tricks, and best practices you’ve learned or discovered while working with it.

Whether you're an experienced developer or just getting started, ObjectScript has its own set of quirks and powerful features—some well-documented, others hidden gems. I’m looking to compile a helpful set of ideas from the community.

Some areas I’m especially interested in:

If you're migrating from Oracle to InterSystems IRIS—like many of my customers—you may run into Oracle-specific SQL patterns that need translation.

Take this example:

SELECT (TO_DATE('2023-05-12','YYYY-MM-DD') - LEVEL + 1) AS gap_date
FROM dual
CONNECT BY LEVEL <= (TO_DATE('2023-05-12','YYYY-MM-DD') - TO_DATE('2023-05-02','YYYY-MM-DD') + 1);

In Oracle:
