Supports program design and generative program building, based on structured programming principles.
Current version: V1.1
COLUMBUS85 provides support for program design and generative program creation, based on the principles of structured programming and including the use of decision tables.
According to the principles of structured programming, a program is constructed as a hierarchy of procedures. Procedures have only one entry and one exit, and in turn consist of structure blocks. In terms of internal control flow, there are only three forms of structure block (sequence, selection, repetition). Decision tables are a special form of structure block used for selection. Structure blocks can be strung together and nested inside each other. Structure lists are the best way of showing these forms.
COLUMBUS85 processes programs in which the control flow/structure is described by COBOL85 or COLUMBUS instructions
