1 Cylinder = 15 Tracks and 1 Track=192KB

aki88

• Apr 13th, 2016

The answer to 1 track = ? bytes, depends entirely on what type of DASD is being used.
If it is 3390 series DASD, then for models 1/2/3/9/, maximum data length/track = 56664 (bytes), and not 196608 bytes.

Based on which scenario , we can prefer static or dynamic call for our program?

PK.Ganapathy

• Jan 7th, 2015

Some of it depends on shop standard. The shops I have worked on prefer keeping subroutines as dynamic. This keeps the region usage low and loading modules to memory as needed. Static increases load module size.

Mangesh K

• Jun 20th, 2012

There are various scenarios based on which we can go for either static or dynamic:
1. When module is big then (i.e. module contains lot of lines) static is better.
2. Simplicity is achieved via static call
3. Dynamic call is prefer when module size is less and modules being frequently compiled
