while

while expr, instructions,..., end
while expr do instructions,..., end
while expr then instructions,..., end

Description

The while clause must be terminated by "end".

Notes:

• The only constraint is that each then or do keyword must be on the same line as while keyword.

• Keywords then or do can be replaced by a carriage return or a comma. For compatibility with Matlab it is also possible, but not recommended, to put a space between the end of the expression and the beginning of the first instruction.

According to the Code Conventions for the Scilab Programming Language it is recommended:

• Start each statement on a new line.

• Write no more than one simple statement per line.

• Break compound statements over multiple lines.

For example, use:

rather than

History

Version	Description
6.0.0	The [,else instructions] syntax is no longer supported. while is now protected: Assignments like while=1 are no longer possible. The number of characters used to define the body of any conditional instruction (if, while, for, or select/case) is no more limited to 16k.
