Hexadecimal signed integers. &H10BF332E, &10BF332E
Hexadecimal unsigned integers. &H8000&, &HFFFF&

String escape characters

The string constants can contain the following escape characters:

Escape character ASCII equivalent
\n Chr$(13)
\r Chr$(10)
\t Chr$(9)
\b Chr$(8)
\v Chr$(11)
\f Chr$(12)
\e Chr$(27)
\0 Chr$(0)
\" Double quote
\\ Backslash
\xNN Chr$(&HNN)

Multi-line string constants

You can write a string constant in several successive parts, even on several different lines.

For example,

"Gambas" " is " "great"


" is "

are absolutely the same constants as

"Gambas is great"
