11-divide-25 — 25-Division File Splitter

电信业务场景

明细25分割。将请求书明细行按25件一个文件进行分割。

Demonstrates dividing input records into groups of 25:

• PERFORM VARYING counter: Track record numbers across the loop
• DIVIDE ... GIVING REMAINDER: Calculate file number from record count
• Close-write cycle: Close old file, open new file at each boundary
• Tested at boundary conditions: 25 (exact), 26 (one extra), 24 (one short)

Files

File	Purpose
main-11-divide-25.cbl	COBOL program (fixed format)
data-gen.sh	Generate N test records (default 26)
run.sh	Compile + run 3 test cases

Algorithm

DIVIDE record-count BY 25 GIVING Q REMAINDER R
IF R = 1 → open new FILE-OUT-NN
Write record to current file

Output Files

• FILE-OUT-01.DAT: records 1-25
• FILE-OUT-02.DAT: records 26-50
• etc.
