Call Routines 0–68 12
12 -12
Use CALL 19 to disable the Ctrl
+ C break function for LIST (page
10 -9) and RUN (page 10 -19) operations. Execute CALL 19 in a BASIC
program or from Command mode. Cycling power returns the Ctrl
+ C
function to normal operation if you disable it from the Command mode.
Important: Ctrl
+ C is enabled by default.

CALL 19
Example
> 90 CALL 19
Use this routine to convert BASIC floating point to 3-digit PLC BCD
number. See also CALL 10.
See Chapter 8 for more information.
Input and Output Arguments
This routine has two input arguments and no output arguments. The first
input argument is the variable with a value in the range of +999 that you
want to convert to signed 3-digit BCD format. The second input argument
is the number of the word (1–64) to receive the converted value in the
block-transfer-read buffer. The sign bit is bit number 16.
Syntax
PUSH data to be converted
