24.5.4 Performing operations on system members

A variety of operations can be performed on any number of nodes selected in the Graph area. If no system nodes are selected, or if you are in another view, the commands are performed on the current system, whose name is printed in the System area.

The Systems menu gives you access to the standard actions described in Performing operations on selected objects.

• Choose Systems > Parent to browse the parent system. This takes you up one level in the hierarchy.
• Choose Systems > Compile and Load , Systems > Compile , or Systems > Load to compile or load the selected systems.
• Choose Systems > Concatenate... to produce a single fasl file from a system. You will need to supply the name of the fasl file, when prompted.
• Choose Systems > Search Files... to search the files of the selected systems (and any subsystems) for a given regular expression. A dialog prompts for the regular expression, and then a Search Files tool is raised in System Search mode, displaying the results of the search. The Search Files tool is described in The Search Files tool.
• Choose Systems > Hide Files , to remove system member files from the graph and display only systems. Choose Systems > Show Files to reverse this effect.
• Choose Systems > Replace to search all the files in the selected members (and any subsystems) for a given string and replace it with another string. You are prompted for both strings in the echo area.

You need to save the buffers to actually save the changes on disk, this is easily done using the Editor tool - see Buffers area for details.
