STRESCAPE - change the string escape character.

$*$STREscape char: lets you change the string escape character. The string escape character is used to indicate escape sequences inside strings. For example, if the string escape character is '*', a new-line is written as '*n'; if the character is '\', a new-line is written as '\n'.
The default string escape is '*' on GCOS8 and '\' on other systems. For maximum portability, an EXEC file should explicitly set its string escape to the character that will be used in the rest of the file.
