New Date Intrinsics for MPE/iX
HPDATECONVERT
This intrinsic converts the dates from one supported format to another.
Syntax
I32V * I32V * I32 I32V
HPDATECONVERT(inputcode,inputdate,outputcode,outputdate,status,cutoff)
Parameters
inputcode 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.”
inputdate varies for type by reference.
The interpretation depends upon the value of inputcode.
See the table, “Supported Date Formats,” for the
supported date codes and their layouts.
outputcode 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.”
outputdate returns the date as per the format chosen by the
outputcode parameter.
See the table, “Supported Date Formats,” for the
supported datecodes and their layouts.
status is the HPE_STATUS parameter through which the error
codes are returned. A value of 0 indicates no error and
no warnings.
cutoff is a 32-bit signed integer by value (optional).
This is used in validating the input parameter when
the input date has two-digit year. This is a required
parameter for dates with two-digit years. In all other
cases, this parameter is ignored.
If the cutoff parameter is given as -1, the value of the CI
environment variable HPSPLITYEAR is used as the
cutoff year.
This parameter's value should be in the range 0 .. 100.
If the value of the parameter is 50, two digit years in
the range 0 .. 49 will translate to 200 .. 2049 and those
in the range 50 .. 99 will be translated to 1950..1999. If
you specify the cutoff year as 70, the mapping will be
0 .. 69 as 2000 .. 2069 and 70 .. 99 as 1970 .. 1999.
