Anyone know of a way to clear everything (variables, values) in IDL?
Seems like there is no such command avaiable.

Yes,
This is my solution of this problem, it's a bit tricky.
The first step may be to identify which variables are defined.
vars=routine_names(variables=-1)
the next step should be to temporary each to dummy
like:
a=execute('dummy = temporary('+vars(i)+')')
but now to the routine,
it's decided as a main program or whithout the end at the end as
@ journal
======================================================
catch,errvar
IF errvar NE 0 THEN GOTO, help
zvars=routine_names(variables=-1)
a = n_elements(a) ; to undefine a
z = n_elements(z) ; to undefine z
zn=n_elements(zvars)-1
for z=0,zn do begin
varvalue=routine_names(zvars(z),fetch=-1)
IF n_elements(varvalue) GT 0 THEN begin
exec = 'dummy = temporary('+zvars(z)+')
print,exec
a = execute(exec)
ENDIF
ENDFOR
IF n_elements(exec) GT 0 THEN dummy = temporary(exec)
IF n_elements(a) GT 0 THEN dummy = temporary(a)
IF n_elements(z) GT 0 THEN dummy = temporary(z)
IF n_elements(zvars) GT 0 THEN dummy = temporary(zvars)
IF n_elements(zn) GT 0 THEN dummy = temporary(zn)
IF n_elements(varvalue) GT 0 THEN dummy = temporary(varvalue)
help: print,'all deleted'
END
============================================================ ===
limitations:
The first time running it clears all variables.
all other runnings it will only clear previously defined / undefined
variables.
WHY - I don't know!

I did a mistake in the previously posted version thats the new one.
