- Appending to a variable:

- >>> setVar('TEST_append', ' of the emergency broadcast system.', d)

- Prepending to a variable:

- >>> setVar('TEST_prepend', 'virtual/tmake ', d)
- >>> setVar('TEST_prepend', 'virtual/patcher ', d)
- >>> update_data(d)
- >>> print getVar('TEST', d)
- virtual/patcher virtual/tmake virtual/libc
-
- Overrides:
- >>> setVar('TEST_arm', 'target', d)
