VARIANT variable type
The VARIANT variable type is determined by the data type of the last value assignment. It
can be scanned using the ISNUM or ISSTR functions. The VARIANT type is mainly suited to
write either variable names or numerical values to the NC code.
Programming
The data type of variables can be checked:
Syntax: ISNUM
(VAR)
Parameters: VAR Name of the variable whose data type is to be checked.
FALSE =
TRUE =
The result of the scan can be:
not a numerical variable (data type = STRING)
numerical variable (data type = REAL)
Syntax: ISSTR
(VAR)
Parameters: VAR Name of the variable whose data type is to be checked.
FALSE =
TRUE =
The result of the scan can be:
numerical variable (data type = REAL)
not a numerical variable (data type = STRING)
Example
IF ISNUM(VAR1) == TRUE
IF ISSTR(REG[4]+2) == TRUE
