ABSTRACT:
When a first application program raises an error condition, a context switch, in one embodiment, transfers control to one of several Help programs, as selected automatically without user or system operator intervention. Such a first application program operates on a computer system that includes a file system, a data structure in memory, and a processor that executes in sequence an operating system, the first application program, a constructor, and a second application program, for example, a Help program. For each candidate Help program, the constructor looks for prerequisite files in the file system. If a candidate Help program's prerequisites are met, the constructor sets a link value in the data structure that directs a subsequent call from the first application program to the Help program selected by the constructor. In a second embodiment, a general method of developing the first application program for context switching incorporates the step of including, in the first application program, a transfer of control to a destination program identified by a constructor, wherein the constructor, precluding manual direction by an operator, identifies the destination program from several candidates by testing an operational prerequisite.
