  1. PEMROGRAMAN TERSUTRKTUR By: SitiMariyah

  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 lastNameand 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 carachtermemory variable whose symbolic name shall be noNameand 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 totalNameand 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 totalNameand 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. OperasiTanggaldanWaktu CDOW() : menghasilkannamaharidalambahasainggris Logic : ?CDOW(ctod(“tanggal”)) Contoh : ?CDOW(ctod(“3/20/2006”))  Monday CMONTH() : menghasilkannamabulandalambahasainggris Logic : ?CMONTH(ctod(“tanggal”)) Contoh : ?CMONTH(ctod(“3/20/2006”))  March DATE() : menghasilkannilaitanggalsekarang Logic : ?DATE() Contoh : ?DATE()  04/09/2013

  9. OperasiTanggaldanWaktu(2) DATETIME() : menghasilkannilaitanggalsekarang Logic : ?DATETIME() Contoh : ?DATETIME()  04/09/2013 05:30:21 PM DAY() : menghasilkantanggal (1 sd 30) Logic : ?DAY(“tanggal”) Contoh : ?DAY(ctod(“3/20/2006”))  20 DMY() : menghasilkantanggal,bulan,dantahun Logic : ?DMY(ctod(“tanggal”)) Contoh : ?DMY(ctod(“3/20/2006”))  20 March 2006

  10. OperasiTanggaldanWaktu(3) MDY() : menghasilkanbulan, tanggal,dantahun Logic : ?DMY(ctod(“tanggal”)) Contoh : ?DMY(ctod(“3/20/2006”))  March 20, 2006 TIME() : menghasilkan jam sekarangdengan format hh:mm:ss Logic : ?TIME() Contoh : ?TIME()  05:30:21

  11. Operasi Numeric ABS : menghasilkannilaimutlak Contoh : ?ABS(-3)  3 INT() : menghasilkanbilanganbulat Contoh : ?INT(1.9)  1

  12. KonversiTipedanEkspresi ASC() : menghasilkannilai ASCII darikarakter yang menjadiargumen Contoh : ?ASC(“A”)  65 CHR() : menghasilkansebuahkarakter yang nilai ASCII nyadicantumkandalamargumen Contoh: ?CHR(65)  A CTOD() : menghasilkan data bertipetanggalberdasarkan string argumennya Contoh: ?CTOD(“3/20/2006”)  03/20/2006Contoh

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