Microsoft Visual FoxPro 6.0 Programming

Using the several commands and function in a sequence to do a particular job is called a Program.

Memory Variable: A Memory Variable is a location that provides a reference to the storage space where the actual value is stored temporarily. Instead of the actual value, the variable name is used in any operation. Valid characters that are used to give a variable name are as follows: A-Z (26 Letters), a-z (26 Letters), 0-9 (10 digit), _ (underscore).

* The first character of a variable name must be a Letter and the maximum length is 10.

Example: ✖SL NO=0, ✔SL_NO=0.

Data Type of Variable: There are different types of data type such as Numeric, Character, Logical, Date etc. The type of a variable depends on the value that has been assigned to that variable. For example:

  • A=0 (A is Numeric Variable)
  • A=SPACE(10) or ” ” or “AMIT” (A is Character Variable)
  • A= DATE () (A is Date Variable)

Operators: An Operator is a symbol that tells the interpreter (অনুবাদক) / compiler (সংকলনকারী) to perform specific mathematical or logical manipulation. There are three types of operators:

  1. Arithmetic:
    • + : Addition
    • : Subtraction
    • * : Multiplication
    • / : Division
  2. Logical:
    • AND or .AND.
    • OR or .OR.
    • NOT or .NOT.
  3. Relational:
    • > : Greater than
    • < : Less than
    • = : Equal
    • >= : Greater than Equal to
    • <= : Less than Equal to
    • #,!= or <> : Not Equal to

Statement: There are two types of Statement are as follow:

  1. Conditional Statement: When user specify the action which based on conditions, then user use the Conditional Statement. There are two types of conditional statement.
  • If…..Else…..EndIf

Syntax:

IF CONDITIONS

STATEMENT [True]

ELSE

STATEMENT [False]

ENDIF

  • Do Case…..EndCase

Syntax:

DO CASE

CASE CONDITION-1

STATEMENT [True]

CASE CONDITION-2

STATEMENT [True]

OTHERWISE

STATEMENT [False]

ENDCASE

  1. Looping Statement: This statement allow a set of instructions to be performed until a certain condition is reached. There are two types of looping statement.
  • Do While…..EndDo

Syntax:

DO WHILE CONDITION

STATEMENT [True]

ENDDO

STATEMENT [False]

  • For…..EndFor

Syntax:

FOR VARIABLE=N1 TO N2

STATEMENT [True]

ENDFOR

STATEMENT [False]
