 *  $ARGUMENTS$
 *      <nRow>      The row coordinate.
 *
 *      <nCol>      The column coordinate.
 *
 *      <cSay>      Message to display.
 *
 *      <cSayPict>  Character expression of PICTURE displayed.
 *
 *      <cSayColor> Color to be Used for the SAY expression.
 *
 *      <xVar>      An variable/field name.
 *
 *      <cGetPict>  Character expression of PICTURE to get.
 *
 *      <lWhen>     Logical expression to allow GET.
 *
 *      <lValid>    Logical expression to validate GET input.
 *
 *      <xStart>    Lower RANGE value.
 *
 *      <xEnd>      Upper RANGE value.
 *
 *      <cGetColor> Color string to be used for the GET expression.
 *  $RETURNS$
 *      None
 *  $DESCRIPTION$
 *      This command adds a GET object to the reserved array variable
 *      named GETLIST[] and displays it to the screen. The field or variable
 *      to be added to the GET object is specified in <xVar> and is displayed
 *      at row, column coordinate <nRow>, <nCol>.
 *
 *      If the SAY clause is used <cSay> will be displayed starting at
 *      <nRow>,<nCol>, with the field variable <xVar> displayed at ROW(),
 *      COL()+ 1. If <cSayPicr>, the picture template for the SAY expression
 *      <cSay>, is used, all formatting rules contained will apply See the
 *      TRANSFORM I function for futher information.
 *
 *      If <cGetPict> is specified, the PICTURE clause of <xVar> will be
 *      used for the GET object and all formatting rules will apply. See
 *      the table below for GET formatting rules.
 *
 *      If the WHEN clause is specified,when <lWhen> evaluates to a logical
 *      true (.T.) condition, the GET object will he activated otherwise the
 *      GET object will be skipped and no information will be obtained via
 *      the screen. The name of a user-defined function returning a logical
 *      true (.T.) or false ( F.) or a code block may be ,specified in <lWhen>
 *      This clause not activated until a READ command or READMODAL()
 *      function call is issued.
 *
 *      If the VALID clause is specified and <lValid> evaluates to it logical
 *      true (.T.) condition the current GET will be considered valid and
 *      the get operation will continue onto the next active GET object. If
 *      not, the cursor will remain on this GET object until aborted or
 *      until the condition in <lValid> evaluates to true (.T.). The name
 *      of a user-defined function returning a logical true (.T.) or false
 *      (.F.) or it code block may be specified in <lValid>. This clause is
 *      not activated until a READ command or READMODAL( ) function call is
 *      issued.
 *
 *      If the RANGE clause is specified instead of the VALID clause, the
 *      two inclusive range values for <xVar> must be specified in <xStart>
 *      and <xEnd>. Id <xVar> is a date data type,<xStart> and <xEnd> must
 *      also be date data types; if <xVar> is a numeric data type <xStart>
 *      and <xEnd> must also be numeric data types. If a value fails the
 *      RANGE test ,a message of OUT OF RANGE will appear in the SCOREBOARD
 *      area (row = 0, col = 60). The RANGE message may be turned off it the
 *      SET SCOREBOARD command or SET() function appropriately toggled.
 *
 *      NOTE       GET functions/formatting rules:

 *      <table>

 *      @E          Dates will be in British formal: numbers in European format.
 *      @K          Allows a suggested value to be seen within the GET
 *                  area but clears It if any noncu sor key is pressed when
 *                  the cursor is in the first Position in the GET area.
 *      @R          Nontemplate characters will be inserted.
 *      @S<nSize>   Allows horizontal scrolling of a field or variable that
 *                  is <nSize> characters wide.
 *      @X          All negative numbers will be followed by DB
 *      @Z          Displays zero values as blanks.
 *      @!          Forces uppercase lettering
