Zetav is a tool for verification of systems specified in RT-Logic language.
Verif is a tool for verification and computation trace analysis of systems described using the Modechart formalism. It can also generate a set of restricted RT-Logic formulae from a Modechart specification which can be used in Zetav.
With default configuration file write the system specification (SP) to the sp-formulas.in file and the checked property (security assertion, SA) to the sa-formulas.in file. Launch zetav-verifier.exe to begin the verification.
With the default configuration example files and outputs are load/stored to archive root directory. But using file-browser you are free to select any needed location. To begin launch run.bat (windows) or run.sh (linux / unix). Select Modechart designer and create Modechart model or load it from file.
Rating: ★★★★☆ (4/5) “Bercakap Dengan Jin Tamar Jalis” follows the unlikely friendship between Amin , a curious university student from Kuala Lumpur, and Tamar Jalis , a mischievous yet wise jin (spirit) who has been trapped in an ancient jar for centuries. When Amin inadvertently frees Tamar while researching folklore for his thesis, the two embark on a series of nocturnal adventures that blend urban life with the hidden supernatural world of Malaysia. The story weaves together humor, cultural myth, and a subtle moral about respecting the unseen forces that shape our everyday reality. 2. What Works | Aspect | Why It Stands Out | |--------|-------------------| | Cultural Roots | The novel draws heavily from Malay folklore (e.g., jinn , orang bunian , tala ) and integrates them organically into a modern setting. Readers familiar with the myths will appreciate the respectful nods, while newcomers get an accessible primer. | | Voice & Humor | The narrator’s witty, first‑person tone (Amin’s) keeps the pacing lively. Tamar’s sarcastic commentary—often delivered in archaic Malay idioms—adds a layer of comic relief that balances the darker, suspenseful moments. | | World‑building | The author creates a vivid “hidden city” that coexists with Kuala Lumpur’s skyscrapers. Descriptions of secret alleys, night markets, and the “Veil of Fog” are evocative and help the reader visualize the supernatural layer of the city. | | Character Development | Both protagonists evolve: Amin becomes more open‑minded and learns humility; Tamar, despite being centuries‑old, reveals a surprisingly tender side, especially when confronting his own regrets. Their dynamic feels genuine, not just a plot device. | | Thematic Depth | Themes of tradition vs. modernity , respect for the unseen , and the price of curiosity are threaded throughout, prompting readers to reflect on how quickly we dismiss cultural heritage in a fast‑moving world. | 3. Minor Flaws | Issue | Impact | |-------|--------| | Pacing in the Mid‑section | Chapters 7‑10 (the “investigation of the haunted library”) can feel a bit meandering; the plot slows while laying groundwork for later revelations. Some readers may skim these sections. | | PDF Formatting | The PDF (version 15) occasionally suffers from inconsistent line spacing and a few typographical errors that distract from immersion. A clean, final edition would improve readability. | | Predictability of the Climax | While the climax is satisfying, the “final showdown” follows a relatively familiar formula (ritual, betrayal, redemption). Fans of more subversive twists might find it predictable. | 4. Who Will Enjoy It? | Reader Type | Why It Resonates | |-------------|-----------------| | Folklore Enthusiasts | The novel treats Malay mythological beings with authenticity and creativity. | | Urban Fantasy Fans | Those who love stories like Neverwhere (Neil Gaiman) or The Night Circus (Erin Morgenstern) will appreciate the blend of city life and hidden magic. | | Young Adults & College Students | The protagonist’s age and academic background make the narrative relatable for students navigating identity and curiosity. | | Readers Seeking Light‑hearted Horror | While there are eerie moments, the humor keeps the tone from becoming too oppressive. | 5. Overall Verdict “Bercakap Dengan Jin Tamar Jalis” is a fresh addition to Malay‑language urban fantasy. Its strength lies in marrying rich cultural heritage with a contemporary, witty narrative . Despite a few pacing hiccups and some PDF formatting quirks, the story’s heart—rooted in friendship across worlds—shines through. The novel not only entertains but also prompts readers to reconsider the invisible layers of history and belief that surround modern life.
If you enjoy folklore with a modern twist and appreciate a protagonist who learns as you read, give this PDF a try. A later, polished edition (beyond version 15) would make the experience even smoother, but the core tale is already compelling enough to warrant a place on your reading list.

The Zetav verifier expects the input RRTL formulae to be in the following form:
<rrtlformula> : <formula> [ CONNECTIVE <formula> ] ... <formula> : <predicate> | NOT <formula> | <quantifiedvars> <formula> | ( <formula> ) <predicate> : <function> PRED_SYMB <function> <function> : <function> FUNC_SYMB <function> | @( ACTION_TYPE ACTION , term ) | CONSTANT <quantifiedvars> : QUANTIFIER VARIABLE [ QUANTIFIER VARIABLE ] ...Where predicate symbols (PRED_SYMB) could be inequality operators <, =<, =, >=, >, function symbols (FUNC_SYMB) could be basic + and - operators, action type (ACTION_TYPE) could be starting action (^), stop action ($), transition action (%) and external action (#). Quantifier symbols (QUANTIFIER) could be either an universal quantifier (forall, V) or an existential quantifier (exists, E). Connectives (CONNECTIVE) could be conjunction (and, &, /\), disjunction (or, |, \/), or implication (imply, ->). All variables (VARIABLE) must start with a lower case letter and all actions (ACTION) with an upper case letter. Constants (CONSTANT) could be positive or negative number. RRTL formulae in the input file must be separated using semicolon (;).

Verif tool does not deal with direct input. Examples are load from files with extension MCH. Those files are in XML and describes model modes structure and transition between modes. There is no need to directly modify those files. But in some cases it is possible to make some small changes manualy or generate Modechart models in another tool.
