Set bits in one string from another (String class) [introduced in Sirius Mods 7.9]


BitOnString sets bits in one string as indicated by another.

Syntax

%result = string:BitOnString( onBits, [Pad= c])

Syntax terms

%resultA string to receive the result of setting the bits in onBits for string.
string The string to set bits in.
onBits The bits to set.
Pad A single character that indicates the character with which the shorter of the two input strings is to be extended. As many copies of pad are used as is required to make the shorter string as long as the longer. If both strings are of equal length, no padding is required. The default value of pad is '00':x.


Usage notes

  • Using a null string for onBits is an easy way of turning on a specific set of bits for each byte in a string (the pad value).
  • BitOnString is most useful for working with binary data, for example binary data being sent or received with Janus Sockets.
