CP 523
"KB" data format
The CP evaluates the low-order byte of a 16-bit variable as the value for the variable in the
"Constant byte" KB format:
• Byte 3 Value of the 1st variable
• Byte 5 Value of the 2nd variable
• Byte 7 Value of the 3rd variable
"KT" data format
You can use the "KT" format to insert the values of internal timers in a message text. To do so, use
LD TX to load the time in BCD into the accumulator and then transfer it to the CP. Four digits are
always printed out without the seconds unit.

"KFa.b" data format
You can set the following parameters:
• Specify the total number of characters to be printed with "a".
The sign and the decimal point each count as one character.
• Specify the number of places afer the point with "b". This is the same as correcting the
variable by a factor of 10
• In the case of data format "KFa,b", a comma (between thousands) is printed out and, in the
case of "KFa.b", a decimal point.
