# 06-branch-evaluate — EVALUATE Branch Program

## 电信业务场景

套餐类型判定。根据套餐代码(P01/P02/P03)进行EVALUATE分支，按套餐类型分流处理。

Demonstrates GnuCOBOL EVALUATE patterns:

- **EVALUATE with ALSO**: Two-condition EVALUATE on KEY and DATA2
- **EVALUATE TRUE/FALSE**: Evaluate boolean conditions
- **EVALUATE multi-value WHEN**: Multiple WHEN values for same action
- **WHEN OTHER**: Default/catch-all branch

## Files

| File | Purpose |
|------|---------|
| `main-06-branch-evaluate.cbl` | COBOL program (fixed format) |
| `data-gen.sh` | Generate test data |
| `run.sh` | Compile, run, verify outputs |

## Input Record

Same as 05-branch-if: KEY(10) + DATA1(20) + DATA2(10)

## Branch Logic

| KEY Value | Output File |
|-----------|-------------|
| 'A' | FILE-A.DAT |
| 'B' | FILE-B.DAT |
| 'C' | FILE-C.DAT |
| any other | FILE-OTHER.DAT |
