sys.dr_range()

Purpose:

sys.dr_range() allows you to set the start and end range of rcds to be read for a driver.

Usage:

sys.dr_range(<asfile>,<fldcdef>,<sval>,<eval>,<matchtype>);

Arguments:

asfile <asfile> - The asfile name of the driver being run.

integer <fldcdef> - The fld num in asfile to use for setting the range. This should be passed as a CDEFINE.

alpha <sval> - Starting val in range. This must be passed as an alpha. 4C will convert it to the proper type.

alpha <eval> - Ending val in range. This must be passed as an alpha. 4C will convert it to the proper type.

integer <matchtype> - This can be MATCH_FULL or MATCH_PARTIAL only.

Returns:

None

Where Used:

sys.dr_range() can ONLY be called from the DrInit PCL of any driver.

Example:

Description:

sys.dr_range() allows you to specify a range rcds in the driver file by specifying a range of values for ONE field in the driver file. You pass in the start and end values that the field will have and a flag specifying either MATCH_FULL, or MATCH_PARTIAL. MATCH_FULL specifies that trailing blanks for an alpha key must match also. All key fields before the specified field must be set before calling sys.dr_range().
