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
