$ListNewA

Create array of empty $lists

Note: Many $functions have been deprecated in favor of Object Oriented methods. There is no direct OO equivalent for the $ListNewA function, but the feature is implemented in a much more natural way with Collections.

This function creates an array of empty $lists.

The $ListNewA function accepts eight arguments and returns a numeric result. It is a callable $function.

Syntax

[%rc =] $ListNewA(%array, option, start_dim1, size_dim1, - start_dim2, size_dim2, start_dim3, size_dim3)

%rc is set to 0 or to an error indicator.

• The first argument is the array which will contain the identifiers of the $lists which are created. This is a required argument.
• The second argument, if set to the string NOREL, indicates that the contents of the $lists are not to be emptied when a RELEASE ALL RECORDS statement is executed. This is an optional argument.
• The third argument is the start index for the created $list identifiers in the first dimension of the array. This is an optional argument; its default is 1. It must be between 1 and the size of the first dimension of the array.
• The fourth argument is the number of indices for the created $list identifiers in the first dimension of the array. This is an optional argument; its default is the number of indices in the first dimension of the array minus the start index, minus 1 (that is, all of the indices starting with the start index). It must be between 1 and this default value.
• The fifth argument is the start index for the created $list identifiers in the second dimension of the array. This is an optional argument; its default is 1. It must be between 1 and the size of the second dimension of the array.
• The sixth argument is the number of indices for the created $list identifiers in the second dimension of the array. This is an optional argument; its default is the number of indices in the second dimension of the array minus the start index, minus 1 (that is, all of the indices starting with the start index). It must be between 1 and this default value.
• The seventh argument is the start index for the created $list identifiers in the third dimension of the array. This is an optional argument; its default is 1. It must be between 1 and the size of the third dimension of the array.
• The eighth argument is the number of indices for the created $list identifiers in the third dimension of the array. This is an optional argument; its default is the number of indices in the third dimension of the array minus the start index, minus 1 (that is, all of the indices starting with the start index). It must be between 1 and this default value.

Return codes

0 - No errors 1 - Invalid array bound

Usage notes

• All invocations of a particular call to $ListNewA will always set the same values to those elements of the array that are being set. Each time that call is executed, any previous $lists in those elements created by that call are deleted, and a new list is created.
• $ListNewA performs the same processing as $ListNew, but it allows the creation of multiple lists in one call, and it allows you to manage the lists in an array. For example:

  B %I FLOAT %X FLOAT %Y FLOAT %L FLOAT ARRAY(10) %X = $READ('Number of procs to display, up to 10') %Y = $ListNewA(%L, , 1, %X) IF %Y NE 0 THEN PRINT 'Error ' %X ' creating ' %X 'lists' STOP END IF FOR %I FROM 1 TO %X %Y = $ProcOpn($READ('Enter proc name')) %Y = $ProcDat(%L(%I)) END FOR PRINT 'Here are the procs, last requested first:' FOR %I FROM %X TO 1 BY -1 PRINT ' ' PRINT 'Proc number ' %I FOR %Y FROM 1 TO $ListCnt(%L(%I)) PRINT $ListInf(%L(%I), %Y) END FOR END FOR
