Describe variables in memory (variant for Stata 5.0)
----------------------------------------------------

    ^ds5^ [varlist] [ , { ^n^umeric ^s^tring | ^t^ype^(^vartype^)^ }
    { ^h^asval^(a^|^y^|^u^|^n)^ | ^w^ithval^(^value_label_name^)^ } ^d^etail ]

Description
-----------

^ds5^ lists variable names in a compact format (or optionally, in the
same format as ^describe^). It is a variant on ^ds^.


Options
-------

^numeric^ specifies that only numeric variables should be listed.

^string^ specifies that only string variables should be listed.

^type(^vartype^)^ specifies that only variables of type vartype should
    be listed. ^type( )^ may be abbreviated down to as few as one
    character for ^b^yte, ^i^nt, ^l^ong, ^f^loat and ^d^ouble. ^string^
    or any abbreviation of it means string variables of any length, so
    that ^type(str)^ is equivalent to ^string^. ^type( )^ may not be
    combined with ^numeric^ or ^string^.

^hasval(a^|^y^|^u^|^n)^ specifies that variables with or without
    value labels attached should be listed. ^hasval(a)^ or ^hasval(y)^
    means attached and ^hasval(u)^ or ^hasval(n)^ means unattached. The
    variables listed will be a subset of those otherwise specified.
    ^t(int) v(a)^ means int variables with value labels attached.

^withval(^value_label_name^)^ specifies that variables with value label
    value_label_name attached should be listed. The variables listed
    will be a subset of those otherwise specified.

^detail^ specifies that a more detailed listing should be given.
    ^ds5, s d^ is equivalent to ^describe^ with all the string
    variables.
    ^ds5, n d^ is equivalent to ^describe^ with all the numeric
    variables.

^ds5^ saves in global ^vlist^ the names of the variables listed.
