Strings

Strings are a plain sequence of alphanumerical characters - letters, numbers or symbols - which are mostly used for messages, or for identifiers of objects such as projects (documents), actions, buffers, programmers (end devices), etc. They are defined this way:

string name = "characters"; 

Remarks:

• Special characters in the string can be given with a backslash: \n = Line feed, \" = double quote, \\ = back slash.
• Strings can be compared with the == operator, f.i. if (sDocument == "document0") ...
• Strings can be concatenated with the +, += operators, f.i. string s = "Hello " + "World";
• Strings can be repeated with the *, *= operators, f.i. string s = "Hello " * 2;
• Arrays of strings can be defined just as arrays of variables.

Example:

string device_name = "device";
string empty_str = "";
string[] MyStringArray;

The string class has the following functions:

string.length(): int

string.toInt(): int

string.toDouble(): double

Strings can be formatted with the message function and the << pipe operator. The content between %..% is replaced by the pipe in order of appearance, e.g:

message("Variable %p1% has the content %p2%") << "Test" << 12;
// results in the string "Variable Test has the content 12"
