Syntax

While EXPRESSIONINSTRUCTION_LISTWend

• INSTRUCTION_LIST is a list of instructions in a script.
• EXPRESSION is a numeric expression that is considered as true if it is not equal to 0.

Examples

# Example 1 : let's perform a computation with successive approximationsVARIA=INIT_VALUEWhile abs(func COMPUTE(VARIA)-TARGET)>EXPECTED_PRECISIONVARIA=func ITERATE(VARIA)Wend# Example 2 : let's wait until the database is updated or until a limit hour is reachedTIMEOUT="22:00:00"While time$<TIMEOUTSleep 1Break func DATABASE_UPDATED=1Wend

Description

Wend delimits the end of a While loop that iterates a loop as long as:

• The condition given in While statement is true, that is the numeric expression returns a not null value.
• A break instruction has not been executed to interrupt the loop.

If the condition is false at the beginning of the While loop, no iteration will be done, and the execution will directly resume after the Wend.
