OData queries are not working

Hi Folks

Don't you know it - as soon as I posted I went back to trying ODATA - and again nothing worked and then I spotted what seemed to be an insignificant error in the code

"/Sale/Invoice/Item/?$Filter=startswith(Number,'RPWeb')"  doesn't work - this is from MYOB API developers web in which I have found many many errors.

So I went to the link that takes me to the official ODATA 2.0 site and tried this line

"/Sale/Invoice/Item/?$Filter=startswith(Number,'RPWeb') eq true"  doesn't work 

but no joy

"/Sale/Invoice/Item/?$filter=startswith(Number,'RPWeb') eq true"  WORKED!!!!!!

I starred at this for hours and missed the obvious - 'Filter' - doesn't work - 'filter' does - ODATA is case sensitive.

VB.NET - is not case sensitive

VC#.NET is pedantically case sensitive to the extent that a variable named "Filter' is totally different to 'filter

VBasic in Access is NOT

ODATA it seems is - 

I resisted posting for weeks - and as soon as I did - the solution popped out.

Hope my dive into ODATA helps someone - they are fiddly though way, way more than SQL queries.
