Option CStrings {On | Off} |
| Description |
Turns on or off the ability to use C-style escape sequences within strings. |
| Comments |
When
Option CStrings On
is in effect, the compiler treats the backslash character as an escape character when it appears within strings. An escape character is simply a special character that cannot otherwise be ordinarily typed by the computer keyboard. |

With hexadecimal values, the Basic Control Engine stops scanning for digits when it encounters a nonhexadecimal digit or two digits, whichever comes first. Similarly, with octal values, the Basic Control Engine stops scanning when it encounters a nonoctal digit or three digits, whichever comes first. When
Option CStrings Off
is in effect, then the backslash character has no special meaning. This is the default. |
| Example |
Option CStrings On
Sub Main()
MsgBox "They said, \"Watch out for that clump of grass!\""
MsgBox "First line.\r\nSecond line."
MsgBox "Char A: \x41 \r\n Char B: \x42"
End Sub
