Re: Using the same conditioning indicator

I wrote:
most of the
programs I worked on didn't need multiple indicators for SFLDSP and
SFLCLR (one was always the opposite of the other, so a single
indicator sufficed for both) and SFLDSPCTL was not conditioned at all.

I should extend that by saying those programs also used the automatic
SFLEND-handling, and there was no reason to enable SFLEND unless the
subfile was displayed, so SFLEND and SFLDSP also used the same
indicator. SFLCLR used the negation of that indicator, and SFLDSPCTL
was not conditioned. So just the one indicator was needed for all the
subfile conditioning.
