An attribute count expression (ac expression) is any numeric constant or any arithmetic, logical, or string expression that evaluates to a valid numeric value, used to reference an attribute count within statements, functions, and arrays or string variable.
Example(s)
In the example below, 1 is the attribute count expression.
|
readv company.name from customer.file,cust-ID,1 else... |
The variable apos must be numeric; in this case it is a 2.
|
apos = 2 readv company.address from customer.file,cust-ID,apos else... |
The numeric constant 1 indicates attribute 1 of the string in the customer.item variable.
|
customer.item<1> = "test string" |
The arithmetic expression, bpos+i, calculates the attribute position in audit.item.
|
audit.item<bpos+i> = amount.list<bpos> |
