Easytrieve is a programming language for Batch processing.

CICS - Transaction processing, it has its own BMS codes for screens.

Looks like Easytieve to me although I haven't seen a SCREEN parameter before.

Have you tried Google with

screen name linesize rowcount

see what you get

Check the Language Reference Guide. First page of Chapter 7:

The SCREEN statement defines and initiates a SCREEN activity. A SCREEN activity defines a transaction-oriented processing activity under the control of keys pressed by the terminal operator. Statements can also be inserted in screen procedures to retrieve and maintain files and databases.
....
The structure of a SCREEN activity is as follows:
Code:

SCREEN statement
Screen declaration statements:
DEFAULTs (first in declaration section)
KEYs, TITLEs, ROWs (in any order)

Screen procedures (both special-named and user-defined, in any order)
SCREEN activities can be executed by PROGRAM or other SCREEN activities. If a PROGRAM activity is not present, the first SCREEN activity detected is automatically executed. A SCREEN activity continues processing until an EXIT, STOP, or TRANSFER statement is executed. Unicenter CA-Easytrieve issues an error message when compiling a screen activity that does not contain one of these statements.
