Mathcad Prime 8 - ORIGIN in string indexing

Hi everyone

 

Does anyone know if the setting of using ORIGIN in string indexing is stored in any variable? A work around would be to use one of the string functions and check what it returns.

Here is a way to determine the index value used for the first character in a string.

It returns 0 if the option "ORIGIN in strings" is NOT checked and the value of ORIGIN otherwise.

The variable that ORIGIN is stored in is ORIGIN.  You can use ORIGIN as an index value, etc. as in this example:

    Here's an expression that determines the ORIGIN used in strings, and it works in Prime Express:

    With 'ORIGIN in strings' set it produces the value of ORIGIN,

    otherwise it produces 0, regardless of the value of ORIGIN

    Note that you cannot determine the setting of 'ORIGIN in strings' in all cases by comparing ORIGIN with ORIGIN.string.

    If ORIGIN=0, it may be set, or not.

     

    Success!
