Parameters 

varname               The name of the variable to be deleted.

Operation Notes 

Deletes a specific MPE/iX variable, or all variables specified by a
pattern.  If you specify more than one varname, you must separate them
with commas.

You may use the wildcard characters, @, #, ?, and [ ] to specify a set or
range of values.

@                     Specifies zero or more alphanumeric characters, or
                      the underbar character (_).  Used by itself, it
                      specifies all possible combinations of such
                      characters.  Used with other characters it
                      indicates all the possible names that include the
                      specified characters.  @ABC@ specifies all names
                      that include ABC anywhere in the name.

#                     Specifies one numeric character.  A###@ specifies
                      all names that begin with A followed by any three
                      digits, followed by any combination of 0 to 251
                      alphanumeric (or underbar) characters.

?                     Specifies one alphanumeric character.  A?#
                      specifies all three-character names that begin with
                      A, followed by an alphanumeric, followed by a
                      digit.

[ ]                   Specifies a set or range of characters.  The set
                      may appear anywhere in the name.  This range
                      specification is not case sensitive and, therefore,
                      [A-K] is the same as [a-k].  If you specify a null
                      set such as [k-a], MPE/iX reports an error.

                      @[abc]@# =    All names containing A, B, or C and
                                    ending in a single digit.

                      [a-k]@ =      All names that begin with any one of
                                    the letters A through K.

                      [n-a] =       Is not valid and is flagged as an
                                    error.

Use

Examples 

To delete two specific variables, enter:

     DELETEVAR firstvariable, secondvariable 

To delete all variables beginning with a single alphabetic character and
ending with the characters axval, enter:

     DELETEVAR ?axval 

To delete all variables created by the user, enter:

     DELETEVAR @  

To delete a range of variables, for example, those that begin with the
letters P, Q, R, S, or T followed by zero or more characters that end
with the string module.  In the following example variables such as
PMODULE, QMODULE, RMODULE, SMODULE, TMODULE, and TIME_MODULE are all
deleted by entering:

     DELETEVAR [P-T]@MODULE 

MPE/iX predefined variables, which are listed in appendix A, cannot be
deleted.

To delete all variables beginning in T and ending in two digits such as
TMP11, T25, TMP_237 but not T2, enter:

     DELETEVAR T@##
