DELETEVAR

     Deletes one or more MPE/iX variables.

SYNTAX

     DELETEVAR varname [,varname]...[,varname]


NOTE:

This command follows the optional MPE/iX command line syntax.



PARAMETERS

VARNAME             The name of the variable to be deleted.


OPERATION

     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 cannot
delete predefined (system, read only) variables.

You may use 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@ = all names that include ABC
anywhere in the name).

# Specifies one numeric character. A###@ = 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 [A-K] is the
same as [a-k]. If you specify a null set such as [k-
a] then MPE/iX will report 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 would be flagged as an error.

This command is available in a session, job, in BREAK, or
from a program. Pressing [Break] has no effect on this command.


EXAMPLE(S)

     DELETEVAR  firstvariable, secondvariable

Deletes two specific variables.

DELETEVAR ?axval

Deletes all variables beginning with a single alphabetic
character and ending with the characters axval.

DELETEVAR @

Deletes all variables created by the user. Refer to the
SETVAR command.

DELETEVAR [P-T]@module

Deletes a range of variables that begin with the
letters P, Q, R, S, or T followed by zero or more characters
that also end with the string module. Thus variables such
as PMODULE, QMODULE, RMODULE, SMODULE, TMODULE and
TIME_MODULE are all deleted by a single command.

DELETEVAR T@##

Deletes all variables beginning in T and ending in two
digits: TMP11, T25, TMP_237 but not T2.
