find out the lower bound of the current filter (defined by HFilter) on an HFSQL data file, view or query.
find out the minimum value of a chart series.
find out and modify the minimum value for some types of controls.

Example

// Modify the lower bound for row 3 of the Progress Bar column
COL_ProgressBar[3].MinValue = 20

// Print the customers found between "DUPONT" and "DURANT"
RPT_MyFileReport.MinValue = "DUPONT"
RPT_MyFileReport.MaxValue = "DURANT"

// According to the lower bound defined for the edit control,
// change this lower bound
IF EDT_Price.MinValue > 10 THEN
EDT_Price.MinValue = 20
END
