That syntax always bothered me. Logically, if we exit a program at
EXIT PROGRAM, subsequent statements would be meaningless.

Long ago I worked on a CDC 6400 computer with the Scope 3.2 operating
system. My very first COBOL assignment in that environment was to write a
simple subroutine that read a record from a file and did an EXIT PROGRAM.
Someone gave me the Scope statments to compile and instead of a short cpu
time limit it had IIRC all 9's for unlimted amount of cpu time. IIRC the
EXIT PROGRAM occurred in an IF or some other conditional so I coded it
without a period at the end. Unfortunately for me on that COBOL compiler the
official EXIT PROGRAM ends with a period and at least in this particular
code the COBOL went into an infinite loop with not job time limit to stop
it. One particular error meassage was repeated a huge number of times.
