Abstract
Convert columns that contain timetags or angles in hr:min:sec notation into real
value columns that can be plotted, and vice versa.

3 Description
dsconv converts a column that contains time tags or right ascension or declination in hr:min:sec/deg:min:sec
into a real number or vice versa. The data can be put into a new column or an already existing one
provided it has the right type.
4 Parameters
This section documents the parameters recognized by this task (if any).
Parameter Mand Type Default Constraints
column yes column
Column to be converted, e.g. test.t:ahf:t
type yes string time time|ra|dec
Determines the type that is represented by the values in the column.

dir no decode string decode|encode
Decode a string column into real values, or encode a real value into a string column.
newcolumn no string
Name of the output column. Provide a simple string up to 8 char only, not a fully qualied column
specication with colons. The column will be added to the same table if it does not exist already.
5 Errors
This section documents warnings and errors generated by this task (if any). Note that warnings and
errors can also be generated in the SAS infrastructure libraries, in which case they would not be docu-
mented here. Refer to the index of all errors and warnings available in the HTML version of the SAS
documentation.
