Here is an encryption program that i made in Q basic. I basically compiled some prog's i found on the internet.


SCREEN 2: SCREEN 0: CLS

Menu:

LOCATE 1, 15: PRINT "CRYPTOR v1.0"

LOCATE 2, 15: PRINT "by ADAM PERRY & MATT OCHS"

LOCATE 3, 13: PRINT " Main Menu "

LOCATE 5, 10: PRINT "E]ncrypt message"

LOCATE 7, 10: PRINT "D]ecrypt message"

LOCATE 9, 10: PRINT "Q]uit Cryptor"

Loop1:

GOSUB GetKey: IF A$ = "E" THEN GOTO Encrypt ELSE IF A$ = "D" THEN GOTO Decrypt ELSE IF A$ = "Q" THEN GOTO Quit ELSE GOTO Loop1

GetKey:

A$ = UCASE$(INKEY$): IF A$ = "" THEN GOTO GetKey

RETURN

Encrypt:

CLS

PRINT "All information except for the file name is capitalization-snsitive."

PRINT "This means that capitalization will affect the message."

INPUT "Recipiant name"; N$

INPUT "File name"; F$

INPUT "Encrypt code"; C$

CLS

INPUT "Message text: ", M$

OPEN F$ + ".CPT" FOR OUTPUT AS #1

A = 0: B = 0: C = 0: CR$ = ""

DO WHILE A LEN(N$) THEN B = 1

C = C + 1: IF C > LEN(C$) THEN C = 1

D = ASC(MID$(M$, A, 1)) + ASC(MID$(N$, B, 1)) + ASC(MID$(C$, C, 1))

Loop2:

IF D > 255 THEN D = D - 255: GOTO Loop2

CR$ = CR$ + CHR$(D)

LOOP

WRITE #1, CR$: CLOSE

CLS : GOTO Menu:

Decrypt:

CLS

PRINT "All information exept the file name is capitalization-sensitive."

PRINT "This means that capitalization will affect the message."

INPUT "Recipiant name"; N$

INPUT "File name"; F$

INPUT "Encypt code"; C$

CLS : CR$ = ""

OPEN F$ + ".CPT" FOR INPUT AS #1

INPUT #1, CR$

CLOSE

A = 0: B = 0: C = 0: M$ = ""

DO WHILE A LEN(N$) THEN B = 1

C = C + 1: IF C > LEN(C$) THEN C = 1

D = ASC(MID$(CR$, A, 1)) - (ASC(MID$(N$, B, 1)) + ASC(MID$(C$, C, 1)))

Loop3:

IF D < 1 THEN D = D + 255: GOTO Loop3

M$ = M$ + CHR$(D)

LOOP

Menu2:

CLS

LOCATE 1, 15: PRINT "Cryptor v1.0"

LOCATE 2, 15: PRINT "by ADAM PERRY & MATT OCHS"

LOCATE 3, 13: PRINT "Decryption Complete"

LOCATE 5, 10: PRINT "V]iew message"

LOCATE 7, 10: PRINT "S]ave message"

LOCATE 9, 10: PRINT "Main menu"

Loop4:

GOSUB GetKey: IF A$ = "V" THEN GOTO ViewMessage ELSE IF A$ = "S" THEN GOTO Save

IF A$ = "M" THEN GOTO Menu ELSE GOTO Loop4

ViewMessage:

CLS : PRINT M$: GOSUB GetKey: GOTO Menu2

Save:

OPEN F$ + ".TXT" FOR OUTPUT AS #1

WRITE #1, M$

CLOSE : GOTO Menu2

Quit:

CLS : SYSTEM




Well, thats it.

You stringed all your variables wrong, A LEN is also incorrect. If you tried to run it, it would not work, 100% about that. Nice try though.

Nowadays, almost most of us have a smartphone and it is may instead of many equipments, such as camera, MP3/MP4, even TV and computer. It is not only convenient, but also useable. First, if you are a shooting lover, you may take photos whenever you like.
