PCML Restrictions

The following are restrictions imposed by PCML regarding parameter and return value types.
The compile will fail if you generate PCML for a program or module that violates one of the restrictions. The PCML will be generated, but it will contain error messages as comments. For example, if you use a Date field as a parameter, the PCML for that parameter might look like this:
<data name="DATE" type="   " length="10" usage="input" />
<!-- Error: unsupported data type -->
