FNC201 – VAL / Character String to BIN Conversion
Outline
This instruction converts a character string (ASCII codes) into binary data.
On the other hand, EVAL (FNC117) instruction converts a character string (ASCII codes) into floating point data.
On the other hand, EVAL (FNC117) instruction converts a character string (ASCII codes) into floating point data.
→ For character strings, refer to Section 5.3.
→ For EVAL (FNC117) instruction, refer to Section 18.5.

Explanation of function and operation
1. 16-bit operation (VAL and VALP)
1) A character string stored in
and later is converted into 16-bit binary data. The number of all digits of the
binary data acquired for conversion is stored in
, the number of digits of the decimal part is stored in
+1, and the converted binary data is stored in
.
In converting a character string into binary data, the data from
to a device number storing "00H" is handled
as a character string in byte units.
