Module edited_pic 

Edited PIC (numeric editing) decode and encode support. Edited PIC (Phase E2 + E3) decode and encode support

This module implements decode and encode for edited numeric PICTURE clauses following IBM COBOL specifications. Edited PICs include formatting symbols like Z (zero suppression), $ (currency), comma, decimal point, B (blank space insertion), and sign editing (+, -, CR, DB).

The decode algorithm walks the input string and PIC pattern in lockstep, extracting numeric digits and validating formatting symbols. The encode algorithm formats numeric values according to the pattern.

Structs

NumericValue

Decoded numeric value extracted from an edited PIC field.

Enums

PicToken

Pattern tokens for edited PIC clauses.

Sign

Sign extracted from an edited PIC field during decode.

Functions

decode_edited_numeric

Decode edited numeric string according to PICTURE pattern

encode_edited_numeric

tokenize_edited_pic

Tokenize an edited PIC pattern into tokens
