Can any one please help me to understand these two expression?

[vinayakg]

LET eMultiboxShow = 'Index(' & chr(39) & '|' & chr(39)  & ' & Concat(%Multibox, ' & chr(39) & '|' & chr(39) & ') &

    ' & chr(39) & '|' & chr(39) & ', ' & chr(39) & '|' & chr(39) & ' & $1 & ' & chr(39) & '|' & chr(39) &') > 0';

LET eMultiboxLabel = '$2 & ' & chr(39) & ' ' & chr(39) & ' & GetFieldSelections($1, ' & chr(39) & ', ' & chr(39) & ', 3)';

Hi

It depends what is confusing you?

Maybe CHR(39) ?

The ' character is used to mark the start and end of a string. This is OK, unless you want the ' character inside your string. In that case CHR(39) is used to represent the ' character.

Hope that makes some sense.

These script statements will create two variables by evaluating the part right of the equal sign.

To see the resulting variables, run the script:

Index('|' & Concat(%Multibox, '|') &    '|', '|' & $1 & '|') > 0

$2 & ' ' & GetFieldSelections($1, ', ', 3)

These variables are probably used passing parameters in a dollar sign expansion:

HI Richard and Stefan,

Thanks for the reply,

But i am not understanding why so many '|' and why they have used $1

This would be easier to answer if you created an input box with these two variables so you could see what the Let produced.

The | (pipes) are separators for the concat function. $1  a parameter for a parameterised variable expansion. You use it like

     =$(eMultiboxShow('X'))

The above will evaluate the expression with 'X' in the place of the $1.
