Validating numeric fields in cobol

Conditions are used in IF, Evaluate and Perform statements. Given below following is the syntax of Relation condition statements: IDENTIFICATION DIVISION.

The different types of conditions are as follows: IF statement checks for conditions.

A conditional variable is always subordinate to another data item. Conditional name identifies the particular value associated to verify during the flow.

There is no limit to the depth of nested IF statements. If you move an alphanumeric field to a numeric field, this is VALID in '85 ANSI/ISO COBOL *if and only IF* the alphanumeric field contains an INTEGER value (signed or unsigned). ****************************************************************** * E N V I R O N M E N T D I V I S I O N * ****************************************************************** environment division. On the other hand, you can use the Num Val (or Num Val-C) intrinsic functions (with any compiler supporting the '89 ANSI/ISO amendment) to the "numeric" values of an alphnanumeric field that contains spaces, decimal points, comma, (or with Num Val-C) currency signs. This tutorial on how to read a COBOL layout was written specifically for our customers who have had a conversion performed at Disc Interchange and have received a COBOL layout with the data.It is intended to give you enough information to read most simple layouts.Conditional statements are used to change the execution flow depending on certain conditions specified by the programmer. The operand containing greater number of characters is declared greater.
