I am new to Assembler programming and my first assignment is to convert 24 bit assembler programs to 31 bit.
Would like to know what are the considerations for such conversions. What details I need to know about the programs before starting with the conversion?
What changes may be needed in the Assembler programs?
What changes are needed in the calling and called programs?
Any other challenges? |

who is the idiot who assigned this task to a beginner 
unfortunately what You ask for cannot be answered on a forum,
forums are for <quick and dirty> questions/answers
converting from 24 to 31 bits ( wiser consider also the 64 bits implications )
takes more that a few lines to explain
what happened when You googled
the first page of a google search with ( verbatim )
ibm assembler 24 31 bit conversion
returned almost all You need to meditate on !
for example
www-01.ibm.com/support/docview.wss?uid=swg27001514&aid=1
publib.boulder.ibm.com/infocenter/zos/v1r11/index.jsp?topic=/com.ibm.zos.r11.ieaa600/iea2a69051.htm
...
good luck, You will need lots of it
will the converted assembler have to be LE compliant ??? |

You're way in over your head and you're going to need a senior colleague to work with.
Your management should have their head examined assigning a task like this to someone who does not have an Assembler background.
Is this both Batch and CICS?
Do the Batch programs contain DCB's or any other reference which requires 24-Bit addressing?
There's much more to this than just what I've outlined. |

Hello and welcome to the forum,
Yup, you have a rather major task to accomplish 
Are you able to read and understand the assembler code you need to upgrade? If not, suggest you get some beginning assembler training before starting to convert code.
When you are ready to actually modify come code, suggest you pick a moderately basic module for the first time thru. This code should (at most) read and write sequential files (to prevent the risk of damaging anything). When you get stuck, post what you are trying to do and what happened (abend, error message, whatever) and someone may be able to offer a suggestion.
We are not able to teach languages here, but we can help with specific issues.
Good luck
