What is numeric-edited field in COBOL?
Numeric-edited items are classified as alphanumeric data items, not as numbers. Therefore, they cannot be operands in arithmetic expressions or ADD, SUBTRACT, MULTIPLY, DIVIDE, and COMPUTE statements. Numeric-edited items can be moved to numeric and numeric-edited items.
Can we redefine numeric to alphanumeric in COBOL?
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.
How does COBOL check numeric data?
the numeric class check is only valid on pic 9 display and packed-decimal type fields. anytime you use reference modification, the field type is automatically x – alphanumeric. │ one or more signed elementary items. so you can do NUMERIC test on a group as long as none of the elementary items are defined as S9…
What is editing in Cobol?
Editing characters for Integer/Numeric Data Edit characters are used to edit the numeric data before printing in the reports. For example, if you want to display the amount along with $ sign, we can do that using these editing character.
What is PIC Z in Cobol?
The z in the PICTURE clause of Edited-price indicates the suppression of leading zeros. You can define numeric-edited data items to hold national (UTF-16) characters instead of alphanumeric characters.
Can we move numeric field to alphanumeric in COBOL?
Yes. Cobol allows to move Alphanumeric variables to numeric variables.
What is the difference between rename and redefine in COBOL?
REDEFINES VS RENAMES: RENAMES clause is used for regrouping elementary data items and gives one name to it. REDEFINES clause allows you to use different data descriptions entries to describe the same memory area.
How do you check if a value is negative in COBOL?
You use a numeric-edited PICture, and specify at least on “-” (minus sign) in an appropriate place. The “-” position will appear as that character for a negative value, but space will appear instead if positive.
How do you check if a value is low in COBOL?
How to Check ‘Comp Variable’ for Spaces and Low-Values
- COBOL Definition for Comp* Here I use comp-4 to demonstrate. 01 COUNTERS.
- COBOL MOVE Statement. MOVE WS_COUNT TO MY_DATA.
- Resolution to Check for Spaces and Low-Values. IF WS_COUNT_X SPACES or LOW_VALUES MOVE ZEROS TO MY_DATA ELSE MOVE WS_COUNT TO MY_DATA END-IF.
How do you know if an alphanumeric field has numeric value?
Re: Numeric check in Alphanumeric field If any byte is not one of those 11 eleven characters, it is not numeric. If all bytes are spaces / 0 through 9, then you can use the FUNCTION NUMVAL to convert the PIC X(4) variable to a PIC 9(04) variable and the ’12’ would be converted as part of that process.
How to move edited data item to numeric data item in COBOL-85?
Using MOVE verb, we can move numeric edited data item to the numeric data item. This is allowed in COBOL-85. Moving numeric edited item to numeric data item referred to as De-editing of the value. Let’s understand with example. 01 EDITED-DATA PIC ZZ999.999. 01 UNEDITED-DATA PIC 9 (5)V99. MOVE 4356.12 TO EDITED-DATA.
How do I create an edit mask in COBOL?
in COBOL an edit mask is defined to the compiler, which the compiler uses to build the appropriate ‘mask’ and code. you need to define all the edit masks (that you may need) as elementary data items in your data division. that means that you will have code to ‘decipher’ the input numeric data in order to determine what edit mask is needed.
What are the editing symbols for numeric data?
Displaying numeric data You can define numeric items with certain editing symbols (such as decimal points, commas, dollar signs, and debit or credit signs) to make the items easier to read and understand when you display or print them. For example, in the code below, Edited-price is a numeric-edited item that has USAGE DISPLAY.
What is de-editing of the value in COBOL-85?
This is allowed in COBOL-85. Moving numeric edited item to numeric data item referred to as De-editing of the value. Let’s understand with example.
