I thought it was. Several compilers I used in that time frame would
produce warning messages if a reserved word was combined into an
identifier, or if any spaces occured in suspicious places.
(Unfortunately, I know this because I had to check all warnings on
some code which had been written with variable names containing
spaces. Fortunately, six, and later eight, character names didn't
have much room for mischief like this, but I do remember variables
named NO GO and LAST X.)
