Apart from my calendar dilemma, I'm also writing a program that converts roman numerals into arabic numbers. Here's what I have so far:
Whenever I run my program, I always get a syntax error that's related to my read statements. Does anybody know how to fix this?
Code:
DECLARE SUB roman (r$(), a())
DECLARE SUB calendar ()
DECLARE SUB calendar2 ()
DECLARE SUB menu ()
'1/27/05
'Calendar and Numeral Program
'
CLS
DIM r$(13)
DIM a(13)
READ r$
READ a
DO
menu
a$ = INPUT$(1)
SELECT CASE a$
CASE "1"
calendar
CASE "2"
roman r$(), a()
CASE "3"
CASE "4"
CLS
LOCATE 20, 40
PRINT "Goodbye"
END SELECT
LOOP UNTIL a$ = "4"
DATA M, CM, D, CD, C, XC, L, XL, X, IX, V, IV, I
DATA 1000, 900, 500, 400, 100, 90, 50, 40, 10, 9, 5, 4, 1
SUB calendar
CLS
INPUT "Enter a date"; d
INPUT "Enter a month"; m
INPUT "Enter a year"; y
IF m = 1 THEN
m = 13
y = y - 1
END IF
IF m = 2 THEN
m = 14
y = y - 1
END IF
n = d + 2 * m + INT(3 * (m + 1) / 5) + y + INT(y / 4) - INT(y / 100) + INT(y / 400) + 2
x = n MOD 7
IF x = 0 THEN
PRINT "Saturday"
END IF
IF x = 1 THEN
PRINT "Sunday"
END IF
IF x = 2 THEN
PRINT "Monday"
END IF
IF x = 3 THEN
