Help with controlling string elements

Hi All

Has anyone had a few moments to look at my previous query,

I'll really appreciate feedback of any sort to help me start experimenting myself,

I have a general difficulty in understanding how to control single elements within a string. An example,

Code:
XYZ1234      ABCD5678

My expected output is :

Code:
ABCD1234     XYZ5678  (swapping subset of string elements of choice)
XYZ37            ACBD1214 (making calculations using string elements)

,etc

Could someone illuminate on such problems please

Thanks in advance Smilie

PS: I'm a beginner to UNIX

NAME
mv - move or rename files SYNOPSIS
mv [ -i ] [ -f ] [ - ] file1 file2 mv [ -i ] [ -f ] [ - ] file ... directory DESCRIPTION
Mv moves (changes the name of) file1 to file2. If file2 already exists, it is removed before file1 is moved. If file2 has a mode which forbids writing, mv prints the mode (see chmod(2)) and reads the standard input to obtain a line; if the line begins with y, the move takes place; if not, mv exits. In the second form, one or more files (plain files or directories) are moved to the directory with their original file-names. Mv refuses to move a file onto itself. Options: -i stands for interactive mode. Whenever a move is to supercede an existing file, the user is prompted by the name of the file followed by a question mark. If he answers with a line starting with 'y', the move continues. Any other reply prevents the move from occur- ring. -f stands for force. This option overrides any mode restrictions or the -i switch. - means interpret all the following arguments to mv as file names. This allows file names starting with minus. SEE ALSO
cp(1), ln(1) BUGS
If file1 and file2 lie on different file systems, mv must copy the file and delete the original. In this case the owner name becomes that of the copying process and any linking relationship with other files is lost. 4th Berkeley Distribution April 29, 1985 MV(1)
