Writing Programs

* FoxPro has powerful built-in editor for writing and editing.

* It can be invoked from the command window by using the MODIFY COMMAND.

Syntax:

MODIFY COMMAND

Example:

Modify Command journal

(This program will automatically save with the extension .PRG)

Press CTRL + W - To save and close the program window

Executing Program

Programs can be executed by DO command.

Syntax:

DO

Example:

Do journal

When compile the executed file the FoxPro creates an object code program with .FXP extension. If

there are any errors, creates a file an .ERR extension.

INPUT command

It is used to accept Numeric input from the user and store it into a memory variable.

Syntax:

INPUT [] TO

Example:

Store 0 to eno

INPUT "Enter your Enrollment No : " TO eno

? Eno

ACCEPT commandIt is used to accept character input from the user and store it into a memory variable.

Syntax:

ACCEPT [] TO

Example:

Store space (15) to NAM


9/27

ACCEPT "Enter the Name: " to NAM

? "Entered name:NAM

Example 2

clear

SET TALK OFF

Accept "Enter your nane :" to nam

Input "enter your Age : " to age

Accept " enter your city :" to cit

Accept "Enter your Mail id : " to mail

? "******************************************"

? "NAME :: " ,nam

? "AGE :: " ,age

? "CITY :: " ,cit

? "MAIL ID:: " ,mail

? "******************************************"

Setting/restoring the environment

Every FoxPro program includes all commands required to establish the working environment

and restore it to its prior state before the program terminates execution. This is achieved by issuing

some set.

Set notify on/off

Enables the display of certain system messages.

Set talk window

Directors the display of system messages to an user-defined window instead of the system

window. Sets notify should be ON.

Set deleted on/off

Processes records marked for deletion.

Input and output in foxpro

As we already know that data can be entered into tables through the APPEND/BROWSEcommands. Data entry for tables can also be done through programs. There arises a need to display

and accept information in a formatted way.

The @say command is used to place data at a particular screen location and to display data

stored in fields or memory variables. The @get commands is used to retrieve data.

Displaying data


10/27

@say command: -

Syntax: -

@SAY

[Function]

[size


11/27

Y - Allows Only Y, y, N, n

! - Converts letters into uppercase.

* - Displays asterisk in place of leading zeros.

, - Display the comma

. - Display the decimal Point.

Function Clause

You can include the function clause, the picture clause or both to control how is displayed or

printed. A function clause affects the entire expression. It contains only the following function code.

Function code & Purpose

BLeftjustifies numeric data within the display region.

Example:

Clear

Store 75815 to amt

@6,20 say amt function ^


13/27

$

Displays data in currently format. the currency symbol appears before or after the field value

depending on the current setting of set currency. used with numeric data only.

Example:-

Clear

Store 75815 to amt

@6,20 say amt function $

Picture expression can include the following characters:-

X Allows any character.

Y Allows logical Y, y, N and n only. Converts y and n to Y and N, respectively.

! Displays the current currency symbol specified by set currency. By default, the symbol is placedimmediately before or after the field.

* Asterisks are displayed in front of the numeric value. Use with a dollar sign $ for check protection.

. A decimal point specifies the decimal point position.

, A comma is used to specifies digits to the left of the decimal point.

Control Structures

IF statement

If Condition is True Executed and then False Not Executed.

Syntax

If (condition) then

Statement-1

End if

Example

clear

mark =0

@5,5 say " Enter the Mark : " get mark RANGE 0,100

Read

If mark >=40 Then

@10,10 say " You have PASS"

Endif

If.else.endif:-

The commands between if..end if will be executed only if condition is satisfied, otherwise the next


14/27

statement is executed. For every if there must be an end if. Every is matched with the nearest

unmatched if.

Syntax:-

If

Else

End if

Command sequence1 will be executed if a condition is true, if condition is false command

sequence-2 will be executed. Control falls to the next statement in either case, if program I still in

execution.

Example 2

clear

Store 0 to x,y

@5, 5 say " Enter the First value: " get x

@7,5 say " Enter the Second value: " get y

Read

IF x > y Then

@10, 10 say str(x) + is Greater than + ltrim (str(y))

Else@10, 10 say str(x) + " is lesser than " + ltrim (str(y))

Endif

Example 3

clear

Store space(1) to x,ch

@5, 5 say " Enter any Alphabet: " get x

Read

ch =chr(asc(x) +32) && To convert Upper into LowerIF ch="a" .or. ch="e" .or. ch="i" .or. ch="o" .or. ch="u" then

@10,10 say ch + " is a VOWEL "

Else

@10,10 say ch + " is a CONSONANT"

Endif


15/27

NESTED IF: (IF within IF)

clear

store 0 to x,y,z

@5,5 say " Enter No1 : " get x

@7,5 say " Enter No2 : " get y

@9,5 say " Enter No3 : " get z

Read

If x > y then

IF x>z then

@ 15,5 say " X is Greater than y and z"

Else

@15,5 say "X is Greater than Y and Lesser than Z"

Endif

Else

IF Y>Z then

@ 15,5 say " Y is Greater than X and Z"

Else

@15,5 say "Y is Greater than X but not Z"

Endif

Endif

DO CASE

Case Commands are used to check for a specified condition

Syntax:

DO Case

Case =

Statement -1

Case =

Statement -2

OtheriwseStatement -3

End Case

Example:

clear

store 0 to day


16/27

@5,5 say " Enter any number from 1 to 7 " get day

Read

DO CASE

case day = 1

@10,10 say "SUNDAY"

case day = 2

@10,10 say "MONDAY"

case day = 3

@10,10 say "TUESDAY"

case day = 4

@10,10 say "WEDNESDAY"

case day = 5

@10,10 say "THURSDAY"

case day = 6

@10,10 say "FRIDAY"

case day = 7

@10,10 say "SATURDAY"

OTHERWISE

@10,10 SAy "Invalid Input"

EndCase

FOR LOOP

To repeatedly execute a series of lines in a Program. The lines of code b/w FOR and ENDOFR will be executed until the memory variable is equal to the

final condition specified.

Default STEP value is 1.Syntax

FOR = TO STEP

................

................

ENDFOR

Example: 1

CLEAR

FOR I = 1 TO 10


17/27

? I

EndFor

Example: 2

To print the EVEN nos from 2 to 50

CLEAR

FOR I = 2 TO 50 STEP 2

? I

EndFor
