DESAL -- Programmer's String Utilities lexfile. Adds ADBUF$, ASC$,
ATH$, HTA$, RED$, KEYWAIT$, and REV$ to BASIC, and improves the
built-in PEEK$ and POKE.

Size: 718 bytes.

ADBUF$ finds the address of the specified buffer.

ASC$ returns its argument string with all non-printable characters
(ASCII codes 0-31 and 127-255) changed to a period.

ATH$ (ASCII To Hex) converts each byte of a string into two
nibble-reversed hex digits.

HTA$ (Hex To ASCII) converts a string of nibble-reversed hex digits
into the corresponding ASCII string.

RED$ reduces a string by removing all spaces on both ends.

KEYWAIT$ is like KEY$ but it waits for the key in a low-drain mode.

REV$ reverses a string.

PEEK$ and POKE are improved to work anywhere, even on SECURE and
PRIVATE sections of memory.
