This method works to search for a user's escape char:
; FindEscapeChar.powerpro
LOCAL NL, c
FOR(LOCAL i= 2; i<256; i++)
IF(i!=34)DO
NL= EVAL(??"?++ ESC(?"\d"++ FILL("000", i)++ "n", ??\?)++ ??"?)
IF(NL==ESC(?"\n", ?"\"))
BREAK
ENDIF
ENDFOR
IF(i!=256)DO
c= ESC(??\d?++ FILL("000", i), ??\?)
WIN.DebugShow("Escape char= "++ c++ ;;+
" == "++ c++ "d"++ FILL("000", i)++ ?" = "++ c++ ;;+
"x"++ FILL("00", WIN.Hex(i)))
ELSE
WIN.DebugShow(?#No Escape character exists: "*EXEC QuoteEscape OFF"#)
ENDIF
QUIT(c)
