Thanks Michael

You have answered the question perfectly - I need to embed the parameters expected in the function declaration - not in the "normal" FoxPro style of a parameters list after the function declaration.

I have not been able to find what are the possible data types in this form of declaration - is Variant valid, is Logical valid - or should it be Boolean? Is a one-character parameter a String? How are arrays handled? Perhaps you could point me to some information on this?

Also, since I have your attention (thanks again!) can I please ask if you know how to solve the following problem:

I have created a Web Service:

DEFINE CLASS Fishers_AccpacWebInterface AS Session OLEPUBLIC

In certain of the functions I open tables in order to update them, in SHARED mode:

USE tablename> ALIAS <alias> SHARED

I then FLOCK() or RLOCK() as required.

Then I APPEND BLANK and GATHER MEMVAR or REPLACE specific fields.

e.g.

USE ARDATA\ARCUST01 ALIAS a_arcust SHARED
IF FLOCK("a_arcust")   
   SELECT a_arcust
   APPEND BLANK
   GATHER MEMVAR MEMO
   UNLOCK IN a_arcust
ENDIF

When I run the class from VFP by declaring a newobject of the class locally, this code executes perfectly, but when I run it as a Web Server whenever I try to APPEND BLANK or REPLACE I get an error: Error: 1429 OLE IDispatch exception code 0 from Fishers_AccpacWebInterface ....... Cannot update the cursor A_ARCUST, since it is read-only. 111..

Also - how can I "wrap" my own messages in the Web Server class in an XML format so that if I return the messsages they are recognised by the calling program as correct XML messages - I need some sort of STRTOXML() function to turn a simple message into a correctly formatted XML message.

Michael - I will also post the question on the "cannot update the cursor" in the Troubleshooting and the Web Server, and XML forums - in the hope of getting an answer.

Thanks again
