Please tell me the code to solve the following issues:
Using the handle ```` hand thea variable , call the xxx API and retrieve the data. Store the returned table in a variable t`.
Pass variable a to API xxx on remote handle h and save to local variable t:
t:h(“xxx”;a)

I’m unable to complete the following tasks.
Please tell me how.
The reference data for these Options are actually stored on a separate q process that operates as an internal service. This process is restricted in that it only allows calls to it’s APIs.
The two available APIs are the following:
getOptionRef- This API takes as it’s only input a symbol list of Options and returns a table with the associated Reference datagetInstRef- This API takes as it’s only input a list of longs corresponding to Instrument IDs and returns a table with the associated Reference data
This Reference data process is a q process which is accessible on port 5010.
1.4 Using your IPC knowledge, connect to this service and store the open handle in a variable refServiceHandle
1.5 Using the handle refServiceHandle and the uniqueOpts variable we created before, call the getOptionRef API and retrieve the associated Options Reference data. Store the returned table in a variable optRef.
1.6 Now, extract the unique instruments in our new optRef table, and call the getInstRef API to return the Instrument Reference data and store in a table instRef.
