COBOL Batch Process Sequence Manager

PRCSEQ00.cbl — Business Specification Preview

Program Intent

Manages a batch process sequence by initializing process control records, finding the next ready process, checking dependencies, updating process status, and calculating the final sequence return code.

Business Rules

1.Function code validationHigh

The request function must be one of INIT, NEXT, STAT, or TERM. Any unrecognized function routes to the error routine.

↳ 0000-MAIN · EVALUATE TRUE · WHEN FUNC-INIT / FUNC-NEXT / FUNC-STAT / FUNC-TERM / WHEN OTHER

2.Ready process selectionHigh

The next process is selected from the internal process table only when its status is READY.

↳ 2100-FIND-NEXT-READY

3.Dependency enforcementHigh

A process can only proceed when dependency checks leave the return code equal to zero.

↳ 2000-GET-NEXT-PROCESS · 2200-CHECK-DEPENDENCIES

4.Final return code calculationHigh

If any process has errors, return ERROR. If any process remains active, return WARNING. Otherwise return SUCCESS.

↳ 4100-CHECK-FINAL-STATUS

Glossary

LS-FUNCTION—Requested operation for the sequence manager

LS-PROCESS-DATE—Batch processing date

LS-NEXT-PROCESS—Next process selected for execution

WS-PROCESS-TABLE—Internal table of sequenced processes

BCT-STATUS—Batch control status

⚠ Risks & Unknowns

·Copybooks required to fully resolve business constants and record layouts.

What you get back from one file

SpecSculpt returns a business-readable specification preview designed for review, validation, and modernization planning.

Executive Spec

A plain-English summary of what the program does — readable by business analysts, product owners, and architects.

Business Rules

Each rule extracted from the source, written in plain English with a confidence label and source evidence reference.

Glossary

Key data fields, constants, and domain terms found in the code, with plain-English definitions.

Risks & Unknowns

Missing copybooks, unresolved calls, and areas requiring human review — flagged explicitly instead of guessed.

Confidence Labels

Every rule is labeled High, Medium, or Low confidence so teams know what to trust and what to validate.

Source Evidence

Each rule links back to the paragraph, section, or line in the original source that supports it.

Every rule is linked to source evidence. Unknowns are flagged instead of guessed.

Why teams trust the output

Every rule links back to source evidence

No rule is presented without a traceable reference to the paragraph, section, or line in the original code that supports it.

Unknowns are flagged instead of guessed

When context is missing — copybooks, external calls, undefined constants — SpecSculpt surfaces the gap as a risk rather than filling it with an assumption.

Human validation happens before modernization

The output is designed to be reviewed and validated by business analysts and architects before any redesign or migration work begins.

Capabilities

From source code to
business knowledge

Every capability built to recover what legacy systems know — and make it readable, traceable, and validation-ready.

Evidence-Backed Rule Extraction

Generate business rules from legacy source code, with each rule linked to the source lines that support it.

Learn more

Business-Readable Specifications

Translate technical legacy logic into clear summaries for business analysts, product owners, architects, and modernization teams.

Confidence Scoring

Label each extracted rule as High, Medium, or Low confidence so teams know what can be trusted and what needs review.

Risks & Unknowns

Surface missing copybooks, unresolved calls, unclear fields, external dependencies, and areas requiring human validation.

Legacy Language Support

Start with COBOL and expand to RPG, PowerBuilder, VB6, PL/SQL, and other legacy standards.

Export for Review

Export validated outputs to Markdown, PDF, and JSON for documentation, review, and future workflow integration.

Built for legacy systems first

SpecSculpt is designed for modernization teams working with long-lived enterprise platforms. COBOL is the first priority, with support expanding across other legacy languages and standards.

Legacy languages

COBOLRPG / IBM iPowerBuilderVisual Basic 6PL/SQLOracle FormsClassic ASPDelphi / Object Pascal

Also supported

Modern language support is available but not the primary focus.

Workflow

From source code to
validated business knowledge

SpecSculpt helps modernization teams recover the business logic hidden inside legacy systems. Instead of guessing what the code does, teams can review extracted rules, inspect the source evidence, and validate the specification before redesign or migration begins.

Analyze

Paste or upload legacy source code.

Extract

Generate business rules, glossary terms, process flow, and risks.

Trace

Review the source evidence behind each rule.

Validate

Mark rules as accepted, rejected, or needing review.

Modernize

Use the validated specification to guide future-state design.

Deployment

Where your code runs

Cloud

For individual developers and small teams. Paste or upload code and generate business specs in minutes.

Private

For banks, insurers, government, and regulated enterprises. SpecSculpt can run inside your environment on dedicated hardware or private cloud infrastructure. Your source code does not leave your network.

Built for enterprise trust

No training on customer source code

Private deployment available

Source evidence retained for auditability

Human validation built into the workflow

Designed for modernization discovery, not black-box code conversion

Built from real modernization work

Yaroslav Semykin

Founder, SpecSculpt

SpecSculpt was created from real modernization work, not theory. The product is based on hands-on experience recovering business rules from legacy COBOL systems and helping business analysts, product owners, and architects validate what the system actually does before designing the future state.
