HPDATEDIFF

Syntax

              I32V      *          *           I32
  HPDATEDIFF (datecode, firstdate, seconddate, diffindays,
  
    I32     I32V
    status, cutoff);

Parameters

datecode

is a 32 bit signed integer by value

The value should be one of the date type codes listed in the table, "Supported Date Formats."

firstdate

is the first input date

The interpretation depends on the value of datecode.

See the table,"Supported Date Formats," for the supported date codes and their layouts.

seconddate

is the second input date

The interpretation depends on the value of datecode.

See the table,"Supported Date Formats," for the supported date codes and their layouts.

diffindays

is a 32 bit signed integer by reference

The number of days difference between the two dates, computed as: seconddate-firstdate. Thus if seconddate is earlier than firstdate, diffindays will be negative.

status

is a 32 bit signed integer by reference

An HPE_STATUS parameter through which the error codes are returned. A value of 0 indicates no errors and no warnings.

cutoff

is a 32 bit signed integer by value (optional).

This is used in validating and converting the two-digit years to four digit ones before computing the difference. (See HPDATECONVERT documentation for more information.)
