@f23 Clear word in block
This @ code enables a particular word to be cleared in a block that has previously
been read with @f10 or @f11. The block is then automatically written back into the
part program memory.
Syntax:
Input parameters:
Output parameters:
CL 800 reserved word:
Example:
The following block is contained in the machining buffer:
"Z80" (corresponding to word four) is to be cleared by means of @f23.
Input R parameters
R : 4
x
R +1: 90 ("Z")

Example: Combined application of @f20 and @f21
The block is:
In this case"X100" is to be replaced by "X1=R100". "X1=R100" is equivalent to two words.
For this reason two consecutive commercial @s must be used.
– @f20: Change 'X100' into 'X1='
– @f21: Insert "R100"
The following values are assigned to the R parameters:
