1. PEMROGRAMAN TERSUTRKTUR
By: Siti Mariyah

2. MEMORY VARIABLES
firstName = “Tom”  create a cchracter memory
variable whose symbolic name shall be firstName
and assign to the string “Tom” to that variable
lastName= “Jerry”  create a cchracter memory
variable whose symbolic name shall be lastName
and assign to the string “Jerry” to that variable
Display memory  display local variables, foxpro
system variable, windows definition, menu
definition and pop-up windows definition

3. MEMORY VARIABLES (2)
?firstName  dipslay memory variable firstName
?lastName  dipslay memory variable lastName
?”Hello”  display character string-display Hello
?M.firstName  display memory variable
firstName
?M.lastName  display memory variable lastName

4. MEMORY VARIABLES (3)
noName = firstName  create a carachter memory variable whose symbolic name
shall be noName and assign the contents to the contents of variable firstName
Key = 5  creates a numeric memory variable whose symbolic name shall be Key and
assign 5 to that variable
Key = 5.5  creates a numeric memory variable whose symbolic name shall be Key
and assign 5.5 to that variable
Valid = .T.  create a logical memory varible whose symbolic name shall be Valid and
assigns True to that variable
Valid = NOT .F. create a logical memory varible whose symbolic name shall be Valid
and assigns True to that variable
myDay = {12/25/98}  creates a logical memory variable whose symbolic name shall
be myDay and assigns 12/25/98 to that variable

5. STRING FUNCTION AND
MANIPULATION
firstName = “tom”
lastName = “jerry”
noName = “john doe”
The + symbol is used to concatenate
(merge/combine) two or more strings
?”Hello” + firstName  display Hello tom
? firstName + lastName  display tomjerry
? firstName +’ ’+ lastName  display tom jerry

6. STRING FUNCTION AND
MANIPULATION (2)
UPPER FUNCTION
? ‘*‘ + Upper(firstName) + ‘+’  display [TOM]
? ‘*‘ + Upper(“good TimE”) + ‘+’  display [GOOD TIME]
totalName = firstName +’ ’+lastName  create a local
memory variable whose symbolic name shall be totalName
and assigns the contents to tom jerry
totalName = Upper(lastName)+’, ’+Upper(firstName ) 
create a local memory variable whose symbolic name shall be
totalName and assigns the contents to JERRY, TOM

7. STRING FUNCTION AND
MANIPULATION (3)
LOWER FUNCTION
firstName = “TOm”
lastName = “JERry”
noName = “john doe”
? ‘*‘ + Lower(firstName) + ‘+’  display [tom]
? ‘*‘ + Lower(“good TimE”) + ‘+’  display [good time]
totalName = firstName +’ ’+lastName  create a local memory variable
whose symbolic name shall be totalName and assigns the contents to tom
jerry
totalName = Upper(lastName)+’, ’+Upper(firstName )  create a local
memory variable whose symbolic name shall be totalName and assigns the
contents to JERRY, TOM

8. Operasi Tanggal dan Waktu
CDOW() : menghasilkan nama hari dalam bahasa inggris
Logic : ?CDOW(ctod(“tanggal”))
Contoh : ?CDOW(ctod(“3/20/2006”))  Monday
CMONTH() : menghasilkan nama bulan dalam bahasa inggris
Logic : ?CMONTH(ctod(“tanggal”))
Contoh : ?CMONTH(ctod(“3/20/2006”))  March
DATE() : menghasilkan nilai tanggal sekarang
Logic : ?DATE()
Contoh : ?DATE()  04/09/2013

9. Operasi Tanggal dan Waktu(2)
DATETIME() : menghasilkan nilai tanggal sekarang
Logic : ?DATETIME()
Contoh : ?DATETIME()  04/09/2013 05:30:21 PM
DAY() : menghasilkan tanggal (1 sd 30)
Logic : ?DAY(“tanggal”)
Contoh : ?DAY(ctod(“3/20/2006”))  20
DMY() : menghasilkan tanggal, bulan ,dan tahun
Logic : ?DMY(ctod(“tanggal”))
Contoh : ?DMY(ctod(“3/20/2006”))  20 March 2006

10. Operasi Tanggal dan Waktu(3)
MDY() : menghasilkan bulan, tanggal, dan tahun
Logic : ?DMY(ctod(“tanggal”))
Contoh : ?DMY(ctod(“3/20/2006”))  March
20, 2006
TIME() : menghasilkan jam sekarang dengan format
hh:mm:ss
Logic : ?TIME()
Contoh : ?TIME()  05:30:21

11. Operasi Numeric
ABS : menghasilkan nilai mutlak
Contoh : ?ABS(-3)  3
INT() : menghasilkan bilangan bulat
Contoh : ?INT(1.9)  1

12. Konversi Tipe dan Ekspresi
ASC() : menghasilkan nilai ASCII dari karakter yang menjadi
argumen
Contoh : ?ASC(“A”)  65
CHR() : menghasilkan sebuah karakter yang nilai ASCII nya
dicantumkan dalam argumen
Contoh: ?CHR(65)  A
CTOD() : menghasilkan data bertipe tanggal berdasarkan
string argumennya
Contoh: ?CTOD(“3/20/2006”)  03/20/2006 Contoh

13. Konversi Tipe dan Ekspresi (2)
DTOC() : menghasilkan data bertipe string
berdasarkan date argumennya
Contoh: ?DTOC(date())  “03/20/2006”
STR() : menghasilkan nilai string dari numeric
Contoh: ?STR(5)  “5”
VAL() : menghasilkan nilai numeric dari string
Contoh : ?VAL(“5“)  5
