      Today i got one interview call in that he is asking me

      What are the Condition functions in Script side?

      Could some one help me

       

      Thanks in Avance

          Check your manual

          Conditional Functions

          if(condition , then , else)

          The three parameters condition, then and else are all expressions. The first one, condition, is interpreted logically.

          The two other ones, then and else, can be of any type. They should preferably be of the same type. If

          condition is true, the function returns the value of the expression then. If condition is false, the function

          returns the value of the expression else.

          Example:

          if( Amount>= 0, 'OK', 'Alarm' )

          alt(case1[ , case2 , case3 , ...] , else)

          The alt function returns the first of the parameters that has a valid number representation. If no such match is

          found, the last parameter will be returned. Any number of parameters can be used.

          Example:

          alt( date#( dat , 'YYYY/MM/DD' ),

          date#( dat , 'MM/DD/YYYY' ),

          date#( dat , 'MM/DD/YY' ),

          'No valid date' )

          Will test if the field date contains a date according to any of the three specified date formats. If so, it will

          return the original string and a valid number representation of a date. If no match is found, the text 'No valid

          date' will be returned (without any valid number representation).

          pick(n, expr1[ , expr2,...exprN])

          Returns the n:th expression in the list. n is an integer between 1 and N.

          Example:

          pick( N'A''B'4, , , )

          returns 'B' if N = 2

          returns 4 if N = 3

          match( str, expr1 [ , expr2,...exprN ] )

          The match function performs a case sensitive comparison.

          Example:

          match( M, 'Jan','Feb','Mar')

          returns 2 if M = Feb

          returns 0 if M = Apr or jan

          mixmatch( str, expr1 [ , expr2,...exprN ] )

          The mixmatch function performs a case insensitive comparison.

          Example:

          mixmatch( M, 'Jan','Feb','Mar')

          returns 1 if M = jan

          wildmatch( str, expr1 [ , expr2,...exprN ] )

          The wildmatch function performs a case insensitive comparison and permits the use of wildcard characters (

          * and ?) in the comparison strings.

          Example:

          wildmatch( M, 'ja*','fe?','mar')

          returns 1 if M = January

          returns 2 if M = fex

          class(expression, interval [ , label [ , offset ]])

          Creates a classification of expressions. The bin width is determined by the number set as interval. The result

          is shown as a<=x<b, where a and b are the upper and lower limits of the bin. The x can be replaced by an

          arbitrary string stated in label. 0 is normally the default starting point of the classification. This can be

          changed by adding an offset.

          Examples:

          class( var,10 ) with var = 23 returns '20<=x<30'

          class( var,5,'value' ) with var = 23 returns '20<= value <25'

          class( var,10,'x',5 ) with var = 23 returns '15<=x<25'
