3.1 Flexible NC programming
Meaning:
<result>:
GETVARTYP:
<name>:
Example:
Program code
DEF INT result=0
DEF STRING name="R"
result=GETVARTYP(name)
IF (result < 0) GOTOF error
The value 4 is returned as result. This corresponds to the REAL data type.
3.1.1.17

Possible type conversions

The constant numeric value, the variable, or the expression assigned to a variable must be
compatible with the variable type. If this is the case, the type is automatically converted when
the value is assigned.
