+## >>> `%splitDSIntoParts()` macro: <<< <a name="splitdsintoparts-macro"></a> #######################  
+
+The splitDSIntoParts() macro allows to split the `set` dataset into `parts` parts 
+of approximately `NOBS/parts` size in datasets: `prefix1` to `prefixN`.
+
+The splitDSIntoParts() macro internally runs the splitDSIntoBlocks() macro.
+
+Macro covers `BASE` engine (`v9`, `v8`, `v7`, `v6`) and `SPDE` engine datasets.
+
+See examples below for the details.
+
+### SYNTAX: ###################################################################
+
+The basic syntax is the following, the `<...>` means optional parameters:
+~~~~~~~~~~~~~~~~~~~~~~~sas
+%splitDSIntoParts(
+    parts
+  <,set>
+  <,prefix>
+)
+~~~~~~~~~~~~~~~~~~~~~~~
+
+**Arguments description**:
+
+1. `parts`       - *Required*, the number of parts to split data into.
+                   Number of parts must be positive integer.
+
+2. `set`         - *Required/Optional*, the name of the dataset to split.
+                   If empty then `&syslast.` is used.
+
+3. `prefix`      - *Required/Optional*, the name-prefix for new datasets.
+                   If missing then set to `part`.
