RM-COBOL Character Validation Procedure

@teodorgeorge

Hello, My Software Engineering work includes small validation routines where clear return codes matter. I can write the RM-COBOL callable procedure using COBOL 85 syntax, without FUNCTION verbs, and check the passed alphanumeric field for keyboard-legal characters. I will include the indicator and first bad character position so your Database Programming flow can reject or cleanse records. I will also add a small driver program showing the CALL and brief inline comments for testing records from your COBOL database. Best regards, Teo

Hello! Bravion from Cleveland here. I will create a clean, classic COBOL 85 procedure compatible with RM-COBOL that scans each character in the input string against a predefined set of valid keyboard characters using simple PERFORM loops and conditional checks. To handle the challenge of no FUNCTION verbs, I will rely on indexed table lookups and straightforward procedural logic to detect invalid characters and return both a status indicator and the position of the first invalid character. I will also provide a concise driver program demonstrating the CALL interface with clear inline comments for easy integration and testing. Could you please confirm the maximum expected length of the input string? Also, do you have a preferred format for the return indicator (e.g., numeric code or boolean)? If you want high-quality results, please do not hesitate to contact me.

Hello, After reviewing your requirements carefully, I understand that you need a small RM-COBOL routine that validates an alphanumeric field using only classic COBOL 85 syntax, with no unsupported FUNCTION verbs or dialect-specific features. I can create a self-contained subprogram that accepts the text through the LINKAGE SECTION, checks each byte against an explicit table of permitted keyboard characters, and returns both a valid/invalid indicator and the first offending position. I will also include a simple driver program showing the CALL, parameter setup, and expected results. In my opinion, the key challenge is ensuring the code compiles cleanly under RM-COBOL while handling spaces, punctuation, tabs, CR, and LF consistently. I would use PERFORM loops, reference modification where supported, or a safe indexed alternative if your compiler version requires it, with clear inline comments throughout. I have two quick questions: • What RM-COBOL version are you using? • What is the maximum length of the input field? I would be glad to deliver a compact, documented, and easily reusable solution. Best regards, Carlos

Hi there ! I've worked with legacy systems where compatibility matters more than modern shortcuts. I can write a clean RM-COBOL 85 procedure without unsupported FUNCTION verbs. The routine will validate every character, return the first invalid position, and stay easy to CALL from existing programs. I'll also include a small driver program, clear comments, and simple documentation for testing. Budget : $120 Timeline : 2 days

Hi, "RM-COBOL CHARACTER VALIDATION PROCEDURE" — you need a routine that works in RM-COBOL, not code written for another COBOL dialect. I'll write a self-contained COBOL 85 compatible procedure that accepts an alphanumeric field, scans it byte by byte against an allowed keyboard character set, and returns both a valid/invalid flag and the position of the first invalid character. I'll also include a small driver program with a simple CALL example and inline comments. To keep it portable, I'll avoid FUNCTION verbs and other dialect-specific features, relying only on syntax supported by RM-COBOL. That makes it easy to drop into your existing programs without changes. Can you confirm the character set in your environment is standard ASCII, or does your RM-COBOL database use an extended code page that should also be considered valid? Looking forward to working with you.

Hi, Dmytro here from Illinois. The usual culprit in legacy RM-COBOL string validation routines points at reliance on modern Intrinsic Functions (e.g., FUNCTION ORD) or vendor-specific verbs, which fail to compile under strict COBOL 85 RM-COBOL standards and lead to unhandled low-value/high-value control character corruption. My approach to building this modular RM-COBOL character validation routine focuses on: • 80-Column Standard COBOL 85 Subprogram utilizing elementary character-by-character subscripting and an explicit ASCII key map table to avoid modern FUNCTION syntax errors. • Exact Keyboard Printable Range Validation inspecting every byte against valid ASCII printable ranges—including space (32), letters, digits, standard punctuation, Tab (09), CR (13), and LF (10). • Zero-Dependencies Driver Program providing a clean CALL ... USING implementation with returning status codes (0 for valid, 1 for invalid) and the exact 1-based character position of any offending byte. The critical decision hinges on whether you prefer the validation routine to evaluate fixed-length 80/255 byte records or accept a dynamic length field parameter passed in the LINKAGE SECTION. If a short call is easier we can settle the linkage definition and ASCII printable character boundary definitions in ten minutes — otherwise tell me whether your database fields are fixed length, and I'll start on the subprogram code.

@melopgabriel

Hi, You need a small RM-COBOL routine that can be called from existing programs to validate a text field against keyboard-safe characters only. I can build that in classic COBOL 85 syntax, with no FUNCTION verbs, so it will compile cleanly in RM-COBOL. I’ve written similar self-contained validation routines that scan a field, detect the first invalid byte, and return a simple status your program can act on immediately. I’ll keep the code easy to drop in: one callable procedure, clear working-storage, and a small driver program showing the CALL. My approach is to inspect each character in sequence, compare it against the allowed keyboard ranges, and return both a valid/invalid flag and the offending position when needed. I’ll include brief inline comments so the logic is easy to maintain. If you’d like, I can draft the procedure and driver in a format ready to compile. Best regards, Gabriel
