HEIDENHAIN iTNC 530 HSCI - Overwrite String (OVWR)

1824 HEIDENHAIN Technical Manual iTNC 530 HSCI
9.10.4 OVERWRITE String (OVWR)
Syntax: OVWR (OVERWRITE)
Operands: S <arg>
Action:
Save the string from the string accumulator in a string memory. This command
differs from the = command in that the iTNC does not transfer the "string end"
character along with it. In this way you can overwrite the beginning of a string
that is already in the string memory. The memory into which the iTNC is to
copy the string is selected through the argument <arg> after the operand
designation. Permissible arguments: 0 to 99 (string memory S0 to S99). See
also "Operand declaration."
Example:
This example also applies to the string commands L, + and =.
Add a string from the string memory S0 to an immediate string. The result is
to overwrite the contents of string memory S1. Initial state:
Immediate string = HYDRAULICS
String memory S0 = OIL
String memory S1 = COOLANT MISSING
Final status:
String memory (characters)
1128
S0 O I L
S1 COOLANT MISSING

Function STL String accumulator (characters)

Load the immediate
string into the string
accumulator
L S "HYDRAUL." O I L
