Perl variables do not have to be explicitly declared to reserve memory space. The declaration happens automatically when you assign a value to a variable. The equal sign (=) is used to assign values to variables.
2016-01-04 Unlike low-level, typeless languages like assembler, Perl doesn’t treat characters and numbers interchangeably; it treats strings and numbers interchangeably. That means you can’t just assign characters and numbers back and forth. Perl provides Pascal’s chr and ord to convert between a character and its corresponding ordinal value: There is usually no need to convert between numbers and strings in Perl. Numbers and strings are interchangeable: if you use a number in a place that expects a string (e.g. the concatenation operator "."), it will automatically be converted into a string; conversely, if you use a string in a place that expects a number (e.g. arithmetic operators), it will automatically be converted into a number. 2013-08-18 Perl is a loosely typed language and there is no need to specify a type for your data while using in your program.
