String Literals with No Escape Sequences

This section describes string literals with no escape sequences.

Using escape sequences in a string literals allows us to make string literals smart. But escape sequences also require extra effort for us to enter strings that have double quotes or backward slashes. For example, here is a string of a Java command to display the version information on a Windows system:

# a command string on a Windows system
cmd = "\"C:\\Program Files (x86)\\Java\\jre6\\BIN\\java.exe\" -version";

To avoid extra effort on coding escape sequences, H language will support a second format to enter string literals using single-quotes with 2 simple rules:

Examples of "string" literals using single-quotes:

'"C:\Program Files (x86)\Java\jre6\BIN\java.exe" -version';
'Who''s There?';
