/*
PMG 2004.11.12
This is a method that works the same as perl's "chop". It simply
drops the last character of a string. This is useful in the case
of the federated storage handler where I'm building a unknown
number, list of values and fields to be used in a sql insert
statement to be run on the remote server, and have a comma after each.
When the list is complete, I "chop" off the trailing comma
ex.
String stringobj;
stringobj.append("VALUES ('foo', 'fi', 'fo',");
stringobj.chop();
stringobj.append(")");
In this case, the value of string was:
VALUES ('foo', 'fi', 'fo',
VALUES ('foo', 'fi', 'fo'
VALUES ('foo', 'fi', 'fo')

inline void chop()
{
Ptr[str_length--]= '\0';
}
