Note 1

nn is a number from 1 to 99. This length is the maximum length. The number nn may be specified as 1 or 2 numerics, or a valid index name of 2 characters may be used (and its numeric value will be substituted in the variable name).

@@LSTnn will be expanded to include all elements (preceded by a "#" if a non-literal) with their corresponding attributes.

For example:

     GROUP_BY NAME(#PANELDATA) FIELDS(@@LST01) in the template

     may be substituted for in the resulting RDML code by

     GROUP_BY NAME(#PANELDATA) FIELDS((#EMPNO *OUTPUT) #SURNAME

              #ADDR1 #ADDR2)

 

@@LSUnn will be expanded to include all elements with no preceding "#" and no attributes.

Note 2

nn is a number from 1 to 99. This length is the maximum length. The number nn may be specified as 1 or 2 numerics, or a valid index name of 2 characters may be used (and its numeric value will be substituted in the variable name).

yy is a number from 1 to 99. This length is the maximum length. The number yy may be specified as 1 or 2 numerics, or a valid index name of 2 characters may be used (and its numeric value will be substituted in the variable name).

@@LSXnn/yy will be expanded to include the first yy elements (preceded by a "#" if a non-literal) of the list.

For example:

GROUP_BY NAME(#PANELDATA) FIELDS(@@LSX01/03)

 

would result in this RDML code in a template:

GROUP_BY NAME(#PANELDATA) FIELDS(#EMPNO #SURNAME #ADDR1)

 

Note 3

nn is a number from 1 to 99. This length is the maximum length. The number nn may be specified as 2 numerics, or a valid index name of 2 characters may be used (and its numeric value will be substituted in the variable name).

xx is a number from 1 to 99. This length is the maximum length. The number xx may be specified as 1 or 2 numerics, or a valid index name of 2 characters may be used (and its numeric value will be substituted in the variable name).
