WHILE...END

Scripts > Productions > WHILE...END

Similar to the IF structure in a WHILE...END structure the decision whether a branch is executed is done by a boolean expression.

This structure has more exactly the form:

WHILE( boolean expression )

while branch

END

The while-branch is a concatenation or grouping of tokens and semantic actions.

The boolean expression always is interpretable and exportable.

Example

NUMBER

{{

int i = 0, iCount = xState.itg();

}}

WHILE(i < iCount)

ReadData  {{ i++; }}

END

At first the number of following data records is read and then by ReadData the data records are read themselves.

Example:

EmptyBracket ::= "[" "]"

NonEmptyBracket ::= "[" IDENT "]"

WHILE ( EmptyBracket() )

  EmptyBracket {{ iEmptyBracketsCount++; }}

END

NonEmptyBracket

The production EmptyBracket is used as well for parsing as for looking ahead. The empty brackets are counted until the first not empty bracket appears.
