-Currently, by default the :ptr-parameter to cpl-impl:replace-task-code is nil, so when modifying a ptr-cram-function make sure to put a reasonable value there. (TODO: replace the default nil with the current effective compile-time parameter for the modified node.)+By default the :ptr-parameter to cpl-impl:replace-task-code is set to the previously effective value of ptr-parameter that is stored in the task tree node. This either the ptr-parameter in the code slot of the node (if there are no code replacements), or the ptr-parameter in the car object in the code-replacements list of the node. When a task tree node is created and a ptr-parameter is not specified, the default is nil.
  
 In our example here, the compile-time parameter is a string. It can however be anything, including a struct or a list, for when you need to pass on several objects through plan transformation. In our example here, the compile-time parameter is a string.
