[Function] Convert the hexadecimal data in the column specified in operand 2 to a binary and assign the
result to the variable specified in operand 1.
Conversion will be performed for the length set by a SLEN command.
Only the integer part will be converted, with the decimal part being ignored.
If a character-string literal is specified in operand 2, conversion will be performed for the
entire length of the literal.
(Note) Keep the converting length to 8 characters or less.
[Example] SCPY 10 ‘1234’ Set ‘1234’ in column 10.
SLEN 4 Set the converting length to four bytes.
VALH 1 10 Assign 4660, which is a binary converted from hexadecimal
‘1234’ in column 10, to variable 1.
LET 1 100 Assign 100 to variable 1.
LET 2 20 Assign 20 to variable 2.
SCPY 20 ‘ABCD’ Copy ‘ABCD’ to column 20.
SLEN 4 Set the converting length to four bytes.
VALH *1 *2 Assign 43981, which is a binary converted from
hexadecimal ‘ABCD’ in the content of variable 2 (column
20) to the content of variable 1 (variable 100).
