Keep in mind that the above relates to Query/400 -- not Query Manager. (Or did 
the 'Prompted' QM interface get this added to it recently?) The resulting 
*QRYDFN object might however be later converted into a *QMQRY object.

For Query Manager queries, you use SQL for 'Query creation mode' and enter the 
variables directly into the SQL statement through the Edit Query display. (Note 
that once a variable is part of the SQL statement, SQL prompting can no longer 
be done. This is because the variable can become any part of or even all of the 
SQL statement; the prompter has no way to know what you intend to put in there.)

The variable is simply a name preceded by an ampersand, e.g., &VAR1 or 
&MYVARIABLE. There are a few basic rules to variables, but one step at a time.

Commonly, a CL or RPG program will present some formatted display to allow 
nice, neat entry of the values to substitute for the variables. These values 
are then passed into the query through the STRQMQRY SETVAR() parameter.
