No problem, the %inomads object includes properties/methods that can be used to access the argument list that was included with the original URL.
These include:
- %inomads'Url_Arg$(argno)
Returns the URL argument/parameter indicated by argno. If no parameter is present at the specified argno, an Error #42 will be generated.
- %inomads'Url_Arg$(name$)
Returns the value assigned to the specified URL parameter or "" if not set.
- %inomads'Url_Arg_Cnt
Number of parameters found on the URL line.
So for your example you could set
ARG_1$=%inomads'Url_Arg$("arg_1").
