The DELETE command is used to delete variables.
In general, the format is:
DELETE vars / options
The available options are:
||Delete ALL variables in memory.
||The special ALL_ option can be used to delete all variables with an underscore as a final character (see the chapter SHAZAM PROCEDURES in the SHAZAM Reference Manual).
||The ALLDATA option can be used to delete all variables with the exception of character variables. In particular, FORMAT will not be deleted.
