What is a simple application of local variable in string operation ?

Go.  Away.  Unless you have some specific questions about your last couple of posts, just go away.

In the subject you talk about local and global, but your questions are about locals only. Please clarify.

What is a " arithjr operation". I am not familiar with that term.

Local variables offer alternative access to front panel elements (control or indicator). The don't do any "operations", just contain data copies.

Typically you don't need them.

Is that a homework assignment?

Apparently you want a flame war so, I'll answer with appropriate examples 

• Local variables of type string should be avoided. 
• Local variables as arithmetic operators may be part of the pallets; pi, e, I, etc...  elsewhys,  a time offset from  UTC or TAI can be queried from some local institutions <such as Camilla Harris's next home> ... Google it,  the USNO has a purpose 
• F*U may be a good example of a string type global variable.   Use it to censor " creative writing "

1. Don't

2. Don't

3. Store the application version number in a Global Variable and use it to update something on all of your GUI windows so you can easily figure out what version of software is being ran.  This helps a lot when debugging applications that are development or get regular updates.

You. Need. To. Stop. Posting. The. Same. Thing. Over. And. Over.

As has been said, local variables represent front panel data of a specified control or indicator. They have whatever datatype the front panel object has (string, numeric, array, etc). They don't do "operations". The simplest application of a string local variable is a string terminal and it's local variable placed on the diagram. Completely meaningless!
