AFAIK, these aren't documented IBM Assembler Macros and they're probably "In-House" written (IE: Site Specific).

Have you consulted with any of your colleagues?

When you view the source, is there any documentation (comments) within the Macro's themselves regarding their origin and/or usage?

Regards,

I am not an expert in assembler need to convert a assembler programs to cobol program.

I found QENTERS at the starting line of the program

Code:
CA015M04 QENTERS 'CA015M04 - RECORD CREATION AND AMENDMENTS',R11,R10   
CA015M04 AMODE 31                                                       
CA015M04 RMODE ANY                                                 
         SPACE 3       


Please i need the format or need of the instruction to decode into cobol

You asked 15 days ago and You got a reasonable answer

QENTERS and QMVC are not standard IBM macros
ask somebody inside Your organization

at first glance QENTERS looks like a macro to carry on the initial housekeeping in the assembler program
it does not have an equivalent High Level Language equivalent

Hello,

When converting from assembler to cobol, it is not a good proctice to try to convert line by line. . .

A far better approach is to understand what business process is provided by the assembler code and write cobol code that provides the same functionality. Many things in assembler do not have a 1-to-1 equivelent in cobol. The part of the assembler code that requires the best understanding is the implementation of business rules - not "housekeeping" and file definition/access.

Both programs should be able to read the input and produce the exact same output.
