RXS_GetUrlVar()

This subprocedure is used to retrieve variables from the URL that was used to call the current program as a web service.

Variables on a URL are specified in name-value pairs. For example:

http://mysite.com/rxs/mywebservice?customer=1&code=3

In this example, there are two variables: customer and code, and each of them has a value of 1 and 3 respectively.

Note: This API is only meant to be used in a program acting as a webservice. Using it in other programs will throw errors.
