|4.30 Elementary Method "Pseudocode" (PCODE)|
The objective of the method "Pseudocode" (PCODE) is to describe the functionality of a module or of a procedure in a structured way. To realize this, the logic operation (control) is described with predefined word symbols which are mostly adopted from a structured programming language. Either textual descriptions or programming language notations are used for the simple statements.
Means of Representation
Control statements like
To be noted are:
In a top-down procedure the object is described on a relatively high level and by applying the control structures and colloquial phrases for conditions and statements.
In subproduct SW Design (Module).Realization of the SW Component/ SW Module the method Pseudocode is applied for the complete functional description of the SW Component/SW Module.
Subproduct SW Design (Module).Realization of the SW Component/ SW Module is completely covered.
The basic method Pseudocode is applied within the scope of the subproduct SW Design (Module).Exceptional Behavior to describe the error correction actions. Subproduct SW Design (Module).Exceptional Behavior is not completely covered. The documentation of the exceptional cases and of other required parts is not supported by the Pseudocode method.
