Special data types are available to identify date formats:
DC a day count from January 1, 1900 stored as a one or two word
integer
DJ a Julian date stored as a one word integer in the HP date format
DY a character date format of “YYMMDD” or “YYYYMMDD”
DM a character date format of “MMDDYY” or “MMDDYYYY”
DD a character date format of “DDMMYY” or “DDMMYYYY”

If a date is stored in a type that does not meet the requirements
of the date data types shown above, enter an “&”. You will be
prompted for the physical storage format of the date. Enter one
of the following formats:
YYMMDD or YYYYMMDD year-month-day
DDMMYY or DDMMYYYY day-month-year
MMDDYY or MMDDYYYY month-day-year
YYMM or YYYYMM year-month
MMYY or MMYYYY month-year

CONVERSION OR MAPPING?
DATA FIELD CONVERSION/MAPPING (C/m)? [ ]
This prompt will occur if there is a field of type X or U in the
computational expression and the data type for the computed
field is specified as a numeric type
or the computational expression contains a numeric field and the
data type for the computed field is non-numeric.
Enter “C” to have the data converted to the new type.
Enter “M” if the data stored in the field just needs to be
mapped (moved).
1/8/03
Data Types.ppt
The “mapping” situation may arise in IMAGE data bases when
the data portion of a record has been defined as one string,
and the contents of the record have been overlaid into this
string with programs. These “hidden” fields can be mapped
into computational fields when creating procedures.
If mapping (rather than conversion) has been specified for a
field value assignment then the Review listing will show
“=>” instead of “=” to indicate that mapping will be
performed on this computed field.
1/8/03
Data Types.ppt
Generally:
• Take the default data type
• Use conversion when prompted unless
– You know you want the data as it is stored.
1/8/03
Data Types.ppt
Reasons to change the data type
 Matching the data type and storage length of a
key field that is to be used to link one file to
another.
 Converting several bytes from a character
string to a numeric for use in arithmetic
calculations.
 Creating a field with a specific data type and
storage length for an undelimited ASCII output
file.
