Type conversion to STRING (AXSTRING)

The function "type conversion to STRING" allows variables of different types to be used as a

component of a message (MSG).

When using the << operator this is realized implicitly for data types INT, REAL, CHAR and

BOOL (see " Concatenation of strings (<<) (Page 449) ").

An INT value is converted to normal readable format. REAL values convert with up to 10

decimal places.

Type AXIS variables can be converted to STRING using the AXSTRING command.

<STRING_RES> = << <any_type>

<STRING_RES> = AXSTRING(<axis identifier>)

<STRING_RES>:

<axis identifier>:

FRAME variables cannot be converted.

A conversion is made from STRING to REAL using the NUMBER command. The ability to be

converted can be checked using the ISNUMBER command.

A string is converted into the axis data type using the AXNAME command.

<REAL_RES>=NUMBER("<string>")

<BOOL_RES>=ISNUMBER("<string>")

<AXIS_RES>=AXNAME("<string>")

Variable for the result of the type conversion

Variable types INT, REAL, CHAR, STRING and BOOL

The AXSTRING command supplies the specified axis identifier as

Variable for axis identifier

The NUMBER command returns the number represented by the <string> as RE‐

Type STRING variable to be converted
