I am connecting to Micro Focus Rumba ObjectX Pro Control Container (Web based TN3270 emulator) version 6 using WHLLAPI. While I am able to connect, copy string to PS, copy PS to string etc. certain APIs are failing.
Failing APIs are
99 (Convert) - convert row column, to position
32 (FindFieldLength) - Find field length.
My observation is that that APIs which require character(s) as input, does not. The API connection input/output details (for both working and not-working APIs are provided below. Any help to resolve this will be highly appreciated.
