When parsing input from a table, more powerful parsing tools
are required.
ZhbCountAllVars: returns the number of occurrences of
all variables in the input string (ZhbGetInput must have been run
before calling this subprocedure)
ZhbGetVarDetails: returns the following information on
the user-specified nth input variable (out of those counted with
ZhbCountAllVars): variable name, variable occurrence number,
indicator (char 0/1) whether variable was found.
Here is an example of using ZhbCountAllVars and ZhbGetVarDetails
to get details when parsing data from a table. Approve some orders,
enter some comments and submit the form to see how procedure
ZhbGetVarDetails parses out the data.
