NAME

esc - map array(i) into escaped character, if appropriate


SYNOPSIS


c = esc(array, i)

character array(ARB)
integer i              # i may be incremented
character c is returned as the escaped character or array(i)




DESCRIPTION

This function checks array(i) for the existence of an
escape character (as defined by ESCAPE in the general
symbol definitions).
If an escape is found and is appropriate, array(i+1) is
returned as the escaped character.

Escaped n (@n) is mapped into NEWLINE, and escaped t
(@t) is mapped into TAB.

If no escape is found, the function returns array(i).
