13-validation-nodup: Field Validation (No Duplicates)

电信业务场景

CDR字段校验。对CDR记录进行字段值校验，检查通话类型代码是否为有效值(01/02/03)，有效记录输出到GOOD文件，无效记录输出到BAD文件。

Description

Reads FILE-IN and validates FIELD1 against an allowed-value list ('A', 'B', 'C', 'D', 'E'). Records with valid FIELD1 values are written to FILE-OUT-GOOD. Invalid records are written to FILE-OUT-BAD with an error code appended.

Record Layout

Input / Good Output (31 bytes)

Field	Type	Length	Description
FIELD1	PIC X	1	Validation field
FIELD2	PIC X	30	Description / payload

Bad Output (33 bytes)

Field	Type	Length	Description
FIELD1	PIC X	1	Original invalid value
FIELD2	PIC X	30	Original description
ERR-CODE	PIC X	2	Error code ('01')

File	Purpose
main-13-validation-nodup.cbl	Main COBOL program
data-gen.sh	Generate test data
run.sh	Compile, run, verify
README.md	This file

Tests

Test Case	Description
Valid values A-E	All 5 allowed values pass to GOOD
Invalid values X,Y,Z	Non-allowed alpha values go to BAD
Invalid values 1,9	Numeric values go to BAD
Empty FIELD1 (space)	Treated as invalid, goes to BAD
Error code in BAD output	'01' appended to each bad record

Usage

cd 13-validation-nodup
bash data-gen.sh
bash run.sh

Expected Behavior

• 5 valid records in FILE-OUT-GOOD (31 bytes each = 155 bytes)
• 6 invalid records in FILE-OUT-BAD (33 bytes each = 198 bytes)
• Invalid records contain the original data plus '01' error code
