VARIANT variable type
The VARIANT variable type is determined by the data type of the last value assignment. If the
assigned or entered value starts with '-', '+', '.' or a number ('0'-'9'), then the value is interpreted
as numeric. In all other cases as a string.
It can be scanned using the ISNUM or ISSTR functions. The VARIANT type is mainly suited
to the purpose of writing either variable names or numerical values to the NC code.
