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 control 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 control
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
String memory S0
String memory S1
String memory (characters)

S0 O I L
S1 C O O L A N T

Final status:
