IBM DOS/VS COBOL permits an optional TRACK-AREA clause in a SELECT statement (also called file-control-entry:
TRACK-AREA IS integer-1 CHARACTERS
integer-1 is an integer.
This clause increases the efficiency of some file operations on the IBM System/360 Disk Operating System but is meaningless on other systems. ACUCOBOL-GT ignores it to remain compatible with IBM DOS/VS.
You may put a TRACK-AREA clause into a SELECT statement, but only when the compiler is in the IBM DOS/VS compatibility mode.
Put the TRACK-AREA clause in any convenient spot after the ASSIGN clause.
