~ Special character

The tilde (~) is an escape character that causes the AVM to read the following character literally. A tilde followed by three octal digits represents a single character. Use it as a lead-in to enter the special characters shown in the following table. In a procedure, a tilde followed by something other than the items in the following table is ignored. For example, "~abc" is treated as "abc". (This may not work as expected when passing parameters to an include file.) The items in the following table are case sensitive.
