PSID Handling for Functions Requiring Connect

Some functions interact only with the host-connected presentation space. These functions require the Connect Presentation Space (1) function as a prerequisite call. The PSID for these functions is determined by the Connect Presentation Space (1) and the Disconnect Presentation Space (2) functions as follows:

• When there is no host-connected presentation space, these functions do not interact with any presentation space. A return code of 1 is generated.
• When there is one host-connected presentation space, these functions interact with the presentation space specified in the calling data string parameter of the most recent call to the Connect Presentation Space (1) function.
