Can We Move Alphanumeric To Comp3 In Cobol?

In comp-3 data representation is in packed decimal and in alphanum data is stored in ascii form so bcuz of data incompatibility Alphanumeric to COMP-3 data movement is not possible.

How do you move alphanumeric to signed numeric in COBOL?

The NUMVAL and NUMVAL-C functions convert character strings to numbers. Use these functions to convert alphanumeric data items that contain free format character representation numbers to numeric form, and process them numerically. For example: 01 R PIC X(20) VALUE “- 1234.5678”.

Can we move numeric to COMP3 in COBOL?

Any numeric variable (USAGE DISPLAY, COMP, COMP-1, COMP-2, COMP-3, COMP-4, or COMP-5) can be moved to a COMP-3 variable with only truncation and overflow issues possible, depending upon the PICTURE clauses involved.

How do I move from COMP3 to alphanumeric?

You need to take care of it in the following way : Code: 01 WS-A PIC S9(4) COMP-3 VALUE 1234. 01 WS-A-NUM PIC S9(4).

Can we compare numeric to alphanumeric in COBOL?

In the various ISO/ANSI COBOL standards, comparing alphanumeric ( PIC X ) and numeric ( PIC 9 ) is like comparing apples and oranges. There are defined rules. Of course, each compiler has different ways of interpreting the standard.

Can we move alphanumeric to comp?

Re: Alphanumeric to COMP-3 data movement
If you consult your manuals, you’ll find that moving alphanumeric literals to comp-3 fields is not allowed. If you have a numeric value in a PIC X(n) field, redefine it as a PIC 9(n) field. Test that field for being numeric before doing the move. MOVE to the comp-3 field.

Can we move character to numeric field in COBOL?

COBOL static code analysis: Alphanumeric values should not be moved to numeric fields.

Can we move zeros to Comp-3 variable?

MOVE ZERO TO WS-PACKED-GROUP. When you move ZERO/ZEROS/ZEROES to a group level which contains elementary COMP-3 fields (in this example) 12-Bytes of Display-Numeric ZERO (X’F0′) is moved to all three fields, which will eventually cause a S0C7 Data Exception. LE has a storage option to initialize memory to LOW-VALUES.

What is difference between comp and COMP3?

COMP usage stores the data in half word or in full word, depending on the size of the data. COMP3 usage stores 1 digit in half byte (i.e. 4 bits) and a separate 1 bit is reserved for the sign, which is stored at the right side of the data.

Can we move packed decimal to numeric in COBOL?

Resolution. This document describes how packed decimal values (Computational-3) can be converted to numeric values via File Master using COBOL copybooks. The only method to get this done is to use a File Master Reformat data set, aka. REFFILE.

Which is better comp or comp3 in COBOL?

The best choice is Packed-Decimal (COMP-3) and a Sign (S9). Regarding space Packed-Decimal is more effective, as the data is stored as decimal data, one decimal digit in one half byte, as Binary uses one byte oer digit.

Can we move comp3 to comp3?

Re: Move comp-3 to comp-3.
The V in a PICTURE clause represents an implied decimal point (implied as in the decimal point is NOT in the data). So COBOL will align the sending field decimal point and the receiving field decimal point and it will then move data based on that alignment.

Why do we use comp3 in COBOL?

COBOL Comp-3 is a binary field type that puts (“packs”) two digits into each byte, using a notation called Binary Coded Decimal, or BCD. This halves the storage requirements compared to a character, or COBOL “display”, field.

How do you compare alphanumeric values?

An alphanumeric comparison is a comparison of the single-byte character values of two operands.
Comparison of two alphanumeric operands

• For the EBCDIC character set, the EBCDIC collating sequence is used.
• For the ASCII character set, the ASCII collating sequence is used.

Which datatype is used for alphanumeric data?

Data types for Access desktop databases

Is alphanumeric check in COBOL?

COBOL supports variables which are either alphabetic, numeric, or alphanumeric.
Data types and Variables.

Can we redefine alphanumeric with numeric?

For instance, you can store a alphanumeric & a numeric data type at the same location using the Redefines in COBOL. Also, you can redefine alphanumeric to numeric using this clause.

Is alphanumeric a special character?

An alphanumeric password contains numbers, letters, and special characters (like an ampersand or hashtag).

Which datatype is used to accept alphanumeric values in a table?

You can use these SQL data types to store alphanumeric data: CHAR and NCHAR data types store fixed-length character literals. VARCHAR2 and NVARCHAR2 data types store variable-length character literals.

How do I convert a character variable to numeric?

You can use the input() function in SAS to convert a character variable to a numeric variable. This function uses the following basic syntax: numeric_var = input(character_var, comma9.); The following example shows how to use this function in practice.

How do you convert alphanumeric to decimal in COBOL?

As said above, UNSTRINGing and combining didnt work, but REDEFINES works! Get alphanumeric string redefined into two numeric fields to hold and process decimal part and integer part individually. Atlast divide the decimal-total by 1000 and add it to integer-part. Thats it!
