Dont all answer at onceJayWalker said:Well according to the notes in resources by R Ashpole it is a Case Tool which i was confused about. Also::
"Variables form part of the data dictionary of a project. There are 6 considerations for each variable:
i. Entity = data item (as in DFD or context diagram)
ii. Data type
iii. Identifier name (variable name)
iv. Alias (temp rename if required)
v. Processes (in IPO or DFD) which use these variables
vi. Pre set values, restrictions etc"
What is the difference between the Identifier name (iii) and Alias (iv). And could you give me an example of a Pre Set Value? (vi)
An identifier is a name chosen by a programmer to represent a specific element like variables, arrays, files, records, subroutines, modules etc. and cant be reserved words within the language.JayWalker said:Well according to the notes in resources by R Ashpole it is a Case Tool which i was confused about.

A constant value is a value that doesnt change like pi.JayWalker said:So a constant value would be like an integer used for calculations such as averages??
An then what is an Alias?
