Just one thought. Had the calling method process or method ended.

I’m guessing so, because that doesn’t work and results in that error message. A pointer to other array types works fine, but not a pointer array. Sorry. It should work, since you can send pointers to an EoS method, but… it doesn’t. 4D could probably make it work, but they haven’t.

Re: Execute on Server Method Attribute
Steve, I think you're using v15 at least - so, put all those parameters into an object and pass the object as the parameter. This resolves the 'Accessing a missing parameter' error. You can put the arrays directly into the object instead of using pointers. This way the server side method can create the arrays it requires and then simply place them back into the return object. "Return object" you say? OK, in this case you need to pass a single pointer to the parameter object. The server side method does whatever it needs to do. This should not rely on anything beyond the direction of what to do from the object ($1). At the end of the method execution you put the results into an object and them write that object back to the pointer to $1. Here's some psuedo code to illustrate: Eg: MySeverSideMethod(->$obj) // $obj has the dates, text and time variables // MyServerSideMethod c_object($obj) c_pointer($1) $obj:=$1-> // $obj now contains whatever you put in it on the client ARRAY X($aFirstArray;0) ... // do some stuff OBJECT SET ARRAY($obj:"firstArray";$aFirstArray) OBJECT SET ARRAY($obj:"secondArray";$aSecondArray) OBJECT SET ARRAY($obj:"thirdArray";$aThirdArray) ... $1->:=$obj // write $obj back to the pointed to variable The key points are that you can declare the arrays locally in the method so it runs no matter what. Then you simply write those arrays to the object passed in. Alternatively you could have your EOS method return an object with the desired data. I would go with writing the data to the passed object and returning either a boolean (true=it worked) or an error text ($0="This is the error message."). On Sat, Jul 14, 2018 at 7:12 AM Stephen J.

Re: Execute on Server Method Attribute
Does the database compile with compiler option “All variables are typed”? Have you tried assertions to test each parameter has the expected value type (test, date, time, pointer, pointed array type)? The failed assertion will be displayed on the server. > On Jul 14, 2018, at 10:12 AM, Stephen J.

RE: Execute on Server Method Attribute
I'm completely confused... No matter how I send the parameters (pointer, variable, text string) into this method with the EOS attribute enabled, Server is complaining that I'm accessing a parameter that does not exist. I've looked at the documentation and my method follows exactly what is outlined, so why is Server having an issue running this method? Any input is GREATLY appreciated!!!
