COBOL Condition Names (88 Levels)

Code Example

## COBOL Condition Names (88 Levels)

Level 88 items define condition names - named conditions that test if a data item contains specific values.

### Syntax

\`\`\`cobol
01 data-name PIC X(2).
   88 condition-name VALUE 'AA' 'BB' 'CC'.
   88 condition-name-2 VALUE 'XX' THRU 'ZZ'.
   88 condition-name-3 VALUES ARE 'A' THRU 'Z'.
\`\`\`

### Features

- **Multiple values**: `VALUE 'A' 'B' 'C'`
- **Range of values**: `VALUE 'A' THRU 'Z'`
- **Combined**: `VALUE 'X' 'Y' 1 THRU 9`

### Setting Condition Names

Use SET statement:
\`\`\`cobol
SET condition-name TO TRUE
\`\`\`

### Benefits

1. Self-documenting code
2. Easier maintenance
3. Reduces magic numbers/values
4. Cleaner IF statements
5. Changes localized to data definition

### Best Practices

- Use meaningful condition names
- Group related conditions together
- Use for status codes, flags, and categories
