Hex("text")
Hex("num")
Hex("blob")
Char To Hex is an alias.
Hex To Blob("hexstring")
Hex To Char("hexstring", "encoding")
The default encoding for the character string is utf-8. utf-16le, utf-16be, us-ascii, iso-8859-1, ascii~hex, shift-jis, and euc-jp are also supported.
Hex to Number
Char To Blob("string")
Char To Blob("string", "encoding")
The default encoding for the blob is utf-8. utf-16le, utf-16be, us-ascii, iso-8859-1, ascii~hex, shift-jis, and euc-jp are also supported.
Blob To Char("blob")
Blob To Char("blob", "encoding")
The default encoding for the character string is utf-8. utf-16le, utf-16be, us-ascii, iso-8859-1, ascii~hex, shift-jis, and euc-jp are also supported.
Blob Peek("blob", offset, length)
Returns a new BLOB that is a subset of the given BLOB that is length bytes long and begins at the offset. Note that the offset is 0-based.
Hex(string) returns the hexadecimal codes for each character in the argument. For example,
Hex( "Abc" );
"416263"
Hex to Char(string) converts hexadecimal to characters. The resulting character string might not be valid display characters. All the characters must be in pairs, in the ranges 0-9, A-Z, and a-z. Blanks and commas are allowed, and skipped. For example,
Hex To Char( "4142" );
"AB"
Hex and Hex To Char are inverses of each other, so
Hex To Char( Hex( "Abc" ) );
"Abc"
Hex To Blob(string) takes a string of hexadecimal codes and converts it to a binary object.
a = Hex To Blob( "6A6B6C" );
Show( a );
a = Char To Blob("jkl", "ascii~hex")
Blob Peek(blob,offset,length) extracts bytes as defined by the arguments from a blob.
b = Blob Peek( a, 1, 2 );
Show( b );
b = Char To Blob("kl", "ascii~hex")
b = Blob Peek( a, 0, 2 );
Show( b );
b = Char To Blob("jk", "ascii~hex")
b = Blob Peek( a, 2 );
Show( b );
b = Char To Blob("l", "ascii~hex")
Hex(blob) converts a blob into hexadecimal.
c = Hex( a );
Show( c );
c = "6A6B6C"
d = Hex To Char( c );
Show( d );
d = "jkl"
Concat(blob1,blob2) or blob1 || blob2 concatenates two blobs.
e = Hex To Blob( "6D6E6F" );
Show( e );
f = a||e;
Show( f );
e = Char To Blob("mno", "ascii~hex")
f = Char To Blob("jklmno", "ascii~hex")
Length(blob) returns the number of bytes in a blob.
g = Length( f );
Show( g );
g = 6
Any hex code outside the ASCII range (space to }, or hex 20 - 7D) is encoded as the three-character sequence [~][hexdigit][hexdigit]. For example,
h = Hex To Blob( "19207D7E" );
Show( h );
i = Hex( h );
Show( i );
h = Char To Blob("~19 }~7E", "ascii~hex")
i = "19207D7E"
Char To Blob(string) creates a blob from a string, converting ~hex codes. Blob To Char(blob) creates a string with ~hex codes to indicate non-visible and non-ASCII codes.
