I hadn't thought of that. Maybe that was a reason for not recording '1' or '0' instead of 'Y' or 'N'.

That's true, but the only part that won't work is the part where you
code "if MyFlag;". If you change it to "if MyFlag = *ON",
it'll work
just fine.

D x s 10i 0 inz(14)
D MyFlag s 1a
/free

myFlag = ( x = 14 );
... write to file ...

... then later, read MyFlag from file, and ...

if MyFlag = *on;
do stuff
else;
don't do stuff
endif;

So the only thing you have to add above and beyond coding
exactly what David asked for is the "= *on". Is that really
a show-stopper?

I hadn't thought of that either and that convinces me. Why the hell create a kind of pseudo boolean Y or N? In fact, we have one old file, that has Y, N, blank and O recorded. O meaning <Oui>. The blank looks like an error. The program using this field tests for field<>'N'. Luckily, that means different from <no> AND different from <non> and if it ain't blank, it ain't Yes nor Oui!
