Read or write one byte of a string variable. Positions are 1-based; position 1 is the first character.
value = BYTE(strvar, pos) BYTE(strvar, pos) = value
strvar - a string variable or array element pos - byte position 1..255 value - replacement byte 0..255
The read form returns the character code, or 0 when the position is past the end of the string. The assignment form writes the byte; when pos is beyond the current end the string is padded with spaces first.
Example:
S$ = "ABC"
PRINT BYTE(S$, 1)
BYTE(S$, 2) = 90
PRINT S$Source: docs/help/byte.txt inmmcore. On the computer, typeHELP BYTE.
