Thanks for all the responses.  I did try the unset but it didn't work.
Does the command need to be in quotes?
Also I have another question regarding variables.  If a value in a variable
is preceded by several blanks (ie. '                 TRUE'), how do you
strip off those blanks to be left with only the word TRUE?  I know these
are probably very simple questions, but not for a rookie like me.  I
appreciate all the help.  Thanks................Lucy

Assuming, you mean scripts for AIX ;-)

'unset variable' removes "variable" from the current environment.
BTW, 'variable=""' sets variable to an empty string.
