Call Routines 0–68 12
12 -13
Use this routine to convert BASIC floating point to 16-bit binary PLC
number. This routine takes a value between 0 and 65535 and converts it to
its binary representative and stores it in the block-transfer-read buffer in
one word. See also CALL 11.
See Chapter 8 for more information.
Input and Output Arguments
This routine has two input and no output arguments. The first input value
is the data or variable you want to convert to 16-bit binary. The second
input value is the number of the word (1–64) to receive the converted value
in the block-transfer-read buffer.
Syntax
PUSH value to be converted
PUSH word location (1–64) that receives the value
CALL 21
Example
>50 PUSH T :REM THE VALUE TO BE CONVERTED TO 16 BINARY
>60 PUSH 3 :REM WORD 3 IN THE BTR BUFFER GETS THE VALUE T
>70 CALL 21 :REM DO THE CONVERSION
Use this routine to convert a value from BASIC format to a four-digit,
signed, octal PLC value. See also CALL 12.
See Chapter 8 for more information.
Input and Output Arguments
This routine has two input and no output arguments. The first input value
is the data (+7777
8
) or variable you want to convert to 4-digit, signed
octal. The second input value 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 value to be converted
PUSH word location (1–64) that receives the value
CALL 22
Example
>50 PUSH H :REM THE VALUE TO BE CONVERTED TO 4-DIGIT
SIGNED OCTAL
>60 PUSH 3 :REM WORD 3 IN THE BTR BUFFER GETS THE VALUE H
>70 CALL 22 :REM DO THE CONVERSION
