- Thanks to everyone who expressed an interest in a post of FLOW, the
- companion program to FLOPPY. I sent FLOW to comp.sources.misc a couple
- of days ago, but I guess the moderator is on hols, as it hasn't yet
- appeared .... The posting contains code for installation on VMS, Unix
- and CMS operating systems.
-
- To use FLOW, you will need to have installed FLOPPY, which is available
- at various ftp sites (such as gatekeeper.dec.com) under the name "ffccc".
-
- Since there have been a couple of requests recently for "structure
- chart" generators in comp.lang.fortran, I include below a taste of what
- FLOPPY/FLOW can do ... but these are not anywhere near such powerful
- tools as e.g. DECSET from DEC (described by Steve Lionel recently).
- The report extract that follows is the "textual structure chart" for
- the FLOW program itself, as produced by FLOW. (Note that the module
- descriptions appearing at the end of each line are picked from the
- source code itself...)

- Meaning of Symbols:
- -------------------
- . ==> terminal node in the tree
- * ==> external procedure
- > ==> subtree node, expanded below
- + ==> multiply called terminal node
- ] ==> procedure calling only externals
- -------------------------------------------------------------------------
- ? ==> module is in IF clause
- ( ==> module is in DO loop
- *************************************************************************
- EXTERNAL procedure names will not appear

- Node name ==> FLOW
