Hi,

What is the significance of TTR which is shown in the loadlibs?

  	 Menu 	 Functions 	 Confirm 	 Utilities 	 Help

I looked for the meaning of it and it is this:

TTR = Relative Track And Record Address

Relative track and record address on a direct-access
device, where TT represents two bytes specifying the track
relative to the beginning of the data set, and R is one
byte specifying the record on that track.

But how does knowing it helps a programmer?

Who said that that information is there for the [application] programmer?

Unless you are doing Assembler programming using the BLDL macro (or similar constructs), knowing the TTR does you no good. For the Assembler programmer, it can be helpful.

No one but I thought it might have some significance as it is shown to an application programmer.

It is shown to any person who invokes the query whether they be a sysprog or a child minder - although what a child minder would be doing using TSO/ISPF I have no idea!
