| Use function NUMVAL which returns the numeric value represented by the character string |

Hi,
Main purpose of the NUMVAL and NUMVAL-C is to convert alphanumeric data items that contain free-format character-representation numbers to numeric form, and process them numerically. For example:
| Code: |
01 R Pic x(20) Value "- 1234.5678".
01 S Pic x(20) Value " $12,345.67CR".
01 Total Usage is Comp-1.
. . . |
Compute Total = Function Numval(R) + Function Numval-C(S)Use NUMVAL-C when the argument includes a currency symbol or comma, or both, as shown in the example.

You need to make sure the field(s) have valid content before you use them as numeric. If you do not ensure valid numbers, at some point the code will most likely abend. |
