Example of including error checking routines in RunRev code

[william humphrey]

I figured out what was causing the error but I don't know:

1. Why it just started happening.
2. How to fix it.


The cause of the error is whenever I use


VCursor_GetRecords(cursorRef,1,12,tab,return ) into fld "email_list"


and the SQL for the cursorRef is one which returns no records I get the
error. So I need some way to trap


VDatabase_SqlSelect( gDatabase, tSQL ) into CursorRef


and stop the VCursor_GetRecord from running when there are no records.
