ExpCalc (Magic xpa 3.x)

Lets you use the results of one expression inside another expression.

Syntax:

ExpCalc (expression specification)

Parameters:

expression specification – the expression number to execute represented by the EXP literal, such as '2'EXP as a pointer to the second function in the expression list of the current task.

Returns:

The evaluation value of the specified expression.

Examples:

  • ExpCalc('2'EXP) executes expression #2.

Note:

The expression specification may be one of the following:

    Make sure to use the EXP literal and not just the number.
