Answer / madhusudhan
For the above answer posted by Narendra, there are 19
People who told yes, but did they test this or verify.
Create a Char variable of Lenth 5 and Numeric variable of
lenth 5 and see the result .
D Num1 S 5 P 0
D Char1 S 5 A INZ('ABCDE')
C MOVE Char1 Num1
C Num1 DSPLY
Num1 will not give a Decimal Data error , instead it gives
the values Num1 = 12345. If you use eval
C EVAL Num1 = Char1
Eval will fail during compilation itself.
As per my analysis , Decimal Data error occurs when junk
values or special characters are passed to Numeric
variable. ( Ex : !, @ , #.$) . For testing Intialize the
above variable Char1 with atleast one special character and
just see the result.
This is only one example which i have given , and i heard
that during Parameter passing also this occurs , but dont
know in which scenerio , if anyone knows more on Decimal
Data error, kindly plz post.

Answer / narendra
If you have defined any field as numeric and the value
being inserted into that field is character then system
will throw the message "decimal data error".

Answer / priya
Decimal data error occurs primarily when numeric field receives invalid values/numbers. The same goes for the case of parameter passing.
When the file is opened by a program and the record containing the invalid data is read, you will not get an error.
But if the field containing the invalid data is read in the program, and some arithematic operation is performed with that value it gives decimal data error.
For eg by being the Factor1 of a MOVEx operation, or either factor in an ADD, SUB, DIV, MULT etc., or on the right-hand side of an EVAL, or if it is involved in a WRITE or UPDATE operation -- then it will be checked, and then the program will fail.
