- dFLOW's first function is | DO WHILE .NOT. EOF
- to prepare a program flow | W IF X > 0
- diagram, like this one --------------> | W T DO CASE
- | W T CASE X = 1
- W's outline WHILE loops | W T 1 STORE '1' TO Y
- | W T CASE X = 2
- T's and F's show IF conditions | W T 2 STORE '2' TO Y
- | W T OTHERWISE
- 1's, 2's, etc. show CASES | W T O STORE 'O' TO Y
- | W T ENDCASE
- You can turn these letters off, | W T DO PROCESS
- to have just indented listings, | W ELSE
- and/or add line numbers, and/or | W F ? "Found zero value"
- look at just the control statements, | W F RETURN
- (for programs that are too long to | W ENDIF
- fit on a screen), and/or just do a | W SKIP
- quick check for nesting errors. | ENDDO
- ------------------------------------
- You can also prepare a module cross-reference for a full system, and a variable
- concordance with, or without, the flow diagrams. DFINST allows customizing.
