-## `%workpath()` macro <a name="workpath-macro-81"></a> ######

+
+## >>> `%workLib()` macro: <<< <a name="worklib-macro"></a> ####################### 
+
+The `%workLib()` macro creates and assigns a WORK-scoped sub-library.
+
+Purpose:
+
+The macro creates (if needed) and assigns a SAS library as a sub-directory 
+under the current `WORK` location. This is useful for isolating temporary 
+outputs per task while ensuring automatic cleanup at the end of the SAS session.
+Basic engines libraries, like `BASE`, `V*`, and simple `SPDE`, can be set.
+
+### SYNTAX: ###################################################################
+
+The basic syntax is the following, the `<...>` means optional parameters:
+~~~~~~~~~~~~~~~~~~~~~~~sas
+%workLib(lib,<engine>)
+~~~~~~~~~~~~~~~~~~~~~~~
+
+**Arguments description**:
+ 
+- `lib`    - *Required*: Name of a library (and sub-folder) 
+             to create under WORK. The value must be a valid 
+             nonempty SAS libref (8 characters max, starting 
+             with a letter or underscore).
+
+- `engine` - *Optional*, Name of a basic, directory level, 
+             SAS engine, e.g. `BASE`. When empty the default
+             engine is used.
+---
+
+### Details  
+
+- Builds a target path: `<WORK>/<lib>`.
+- All data written to this libref are temporary and will be removed 
+  when the WORK library is cleared at session end.
+- If a directory with the same name already exists under WORK, 
+  the macro prints a note and simply assigns the LIBNAME to 
+  that location.
+- The `dcreate()` function is used to create sub-directory.
+
+ 
+### EXAMPLES AND USECASES: ####################################################
+
+**EXAMPLE 1.** Create basic library ABC:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+  %workLib(abc)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**EXAMPLE 2.** Create libraries with different engines:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+  %workLib(b,BASE)
+
+  %workLib(v,V6) %* for Windows only.;
+
+  %workLib(s,SPDE)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
