UpdHtmlVar's third parameter controls clearing the substitution variables array. 
When you want to start over with a new set of values, specify '0' in the third 
parameter when using UpdHTMLVar for the first variable of the set.

The following is copied from QRPGLESRC member PROTOTYPEB:

 ******************************************************************
 * Prototype for updHTMLvar subprocedure
 ******************************************************************
 * Updates arrays containing variable names and values
 * Inputs
 *  - variable name
 *  - variable value
 *  - action (optional)
 *      - '1' = replace this variable in the arrays if it is already
 *              there. Otherwise add it to the arrays (default).
 *      - '0' = clear arrays and write variable as the first element.
 *  - trim instructions (optional)
 *    - %trim  - trim left and right (default)
 *    - %triml - trim left only
 *    - %trimr - trim right only
 *    - %trim0 - don't trim

D updHTMLvar      pr
D  name                         30    const varying options(*varsize)
D  value                      1000    const varying options(*varsize)
D  action                        1    value options(*nopass)
D  trim                          6    value varying options(*nopass)
