Detailed Description
prefix comment removedParse and represent a Rexx program
The source program is parsed into comments, quoted strings and clauses. Quoted strings are necessary to complete parsing into clauses, since lineend (;) chars may appear in a quoted string
Clauses are then built back up into features, which correspond to the procedures, classes, methods, etc. in the program. Features consist of an undifferentiated list of one or more clauses. Further interpretation is left to other code.
Block comments are merged together when contiguous, and a list is build of code features and block comments ordered by start line
The results of the parse appear as lists of filechunks which the user can traverse and render as source, either code-only, comments-only or code and comments (vanilla source)
A Rexx program consists of a top (or entry) procedure and zero or more labels and procedures. If it's an OORexx program it may have requires clauses, classes, methods or routines
At the first sign of OORexx features (use of the twiddle, or OORexx directives) the procedural flag is set to .false
Since the lists are public, the user can do anything at all with them. Convenience methods are provided in the public method interface as an aid to navigation.
In general, the features and codefeatures lists are likely to be the most useful, followed by the clauses list
