PMADL Usage
Pathmaker Application Definition Language (PMADL)
2–2 067869 Tandem Computers Incorporated
The basic steps for using PMADL are:
1. Invoke PMADL and select the Pathmaker project or catalog that contains the
objects to be worked with.
2. Direct the object descriptions to a file.
3. Make modifications to the file. Also make any necessary modifications to the data
descriptions in the associated DDL output file.
4. Recompile the DDL output file.
5. Recompile the object descriptions into the same project or a different one.
Although you can run PMADL interactively, it operates best if you run it in batch
mode for a project that is already populated with data from using the Pathmaker
screen-based interface. You can run PMADL in the background, send the output to
the spooler, and use PERUSE to look at the spooler output.
The following list provides brief definitions of the PMADL statements and commands,
in an order in which you can use them. Command names start with a question mark.
