COBOL Code Documentation & Analysis

Our COBOL code documentation starts with analysis of complex programs and subroutines and ends with detailed flowchart and pseudocode documentation, almost to the line-by-line level.

Why it matters

Legacy system documentation before key people retire

Decades of business rules live in your COBOL code, and much of it is documented only in the heads of a few experienced people. When they retire, that knowledge goes with them.

We map and document your estate so your team can understand it, change it safely and plan what comes next.

What we do

COBOL code documentation and analysis services

  • Analysis of complex COBOL programs and subroutines
  • Detailed flowcharts and pseudocode documentation
  • Inventories and dependency maps of the estate
  • Program-by-program impact reviews before a change
  • Knowledge capture before key people retire
  • AI-assisted analysis that runs inside your perimeter

In practice

When teams call us

  • Before a modernization or migration decision
  • Before a large mandate touches many programs
  • When the people who know the code are retiring
  • When new developers need to get up to speed
  • When a change keeps breaking something unexpected

FAQ

COBOL code documentation: FAQ

What does COBOL code documentation include?

Detailed flowcharts and pseudocode for complex programs and subroutines, inventories and dependency maps of the estate, and program-by-program impact reviews before a change.

When should we document our legacy systems?

Before a modernization or migration decision, before a large mandate touches many programs, and before the people who know the code retire.

Can AI help document our COBOL?

Yes. We offer AI-assisted analysis that runs inside your perimeter, so your source code never leaves your building. See AI for COBOL.
