convert alphanumeric to numeric
data definitions required
convert-this w 5 a
convert-this-num convert-this 5 n 0
convert-this-byte convert-this 1 a occurs 5 index ctb-x
this-packed w 3 p 0
error-flag 1 1 a
procedure is
error-flag = 'x'
ctb-x = 0
do-while ctb-c < 5
case convert-this-byte
value numeric
error-flag = error-flag
*or any other null action
value ' '
convert-this-byte = '0'
* if there are valid characters that need to be converted - test for them and convert them, in my day it was spaces to the left convert to zero blindly

error-flag = 'y'
end-case
ctb-x = ctb-x + 1
end-do
if error-flag = 'y'
*define an error routine and execute it
else
this-packed = convert-this-num
* move the field to the resulting packed field "this-packed"

What is the relationship between the IRA character code and the packed decimal representation?
As IRA used 8 bits per character . IRA characters are compatible with packed decimal .
What is packed decimal?
Packed decimal is a method used in computing to store more in less space. A bit of theory here. Characters are stored in binary in their ASCII representation, such that the number 1 = ascii 49 (decimal). Packed decimal means you can store two numbers (numbers only) in the same space, so that ascii 49 = numbers 4 and 9. There is overhead so it is always a trade off between space and computing. And storage is cheap these days
What is packed decimal in cobol?
In Cobol, they had a serious concern for memory size. So they came up with a method known as BCD (Binary Coded Decimal), where a decimal value was converted to binary to save space. Check this link out. It will break down the details.
What is the difference between packed bcd and unpacked bcd?
BCD:A byte (unpacked) representation of a decimal digit in the range0 through9. Unpacked decimal numbers are stored as unsigned byte quantities. Onedigit is stored in each byte. The magnitude of the number is determined fromthe low-order half-byte; hexadecimal values 0-9 are valid and areinterpreted as decimal numbers. The high-order half-byte must be zero formultiplication and division; it may contain any value for addition andsubtraction.Packed BCD:A byte (packed) representation of two decimal digits, each in the range0 through 9. One digit is stored in each half-byte. The digit in thehigh-order half-byte is the most significant. Values 0-9 are valid in eachhalf-byte. The range of a packed decimal byte is 0-99.
