Diszo

Diszo grays out all or part of the fields in a mask that were previously activated. Unlike Grizo, Diszo stipulates that these fields have a meaning in the contex.

This function is only usable in Classic pages related code and is deprecated for code running in version 7 mode.

Syntax

   Diszo [CLASS]
   Diszo [CLASS] FIELD_LIST
   Diszo FIELD_LIST
  • FIELD_LIST is a list of FIELDS separated by commas.
  • FIELD can be either a single variable name, or an element in an array with the syntax VARIABLE_NAME (INDEX), where INDEX is an integer values that provides the indexes of the element in the array, or a rank (numeric value), or a range of fields with the syntax VARIABLE_NAME - VARIABLE_NAME, or a range of ranks with the syntax RANK_1 - RANK_2, or a numeric or alphanumeric expression prefixed by =wich computation returns a rank or a field name.
  • If no field is given, all the fields in the mask are grayed out.
  • [CLASS] is the abbreviation that has been used for the mask. If omitted, it is the default mask.

Examples

# Gray out in the current mask the fields of rank 1, 15 to 30
# and of fields CHP1, VAR to FIN.
Diszo 1, 15-30, CHP1, VAR-FIN
# Gray out in the abbreviation mask ABC the fields of rank 20 to 30
# and the field TOTO for index I+1.
Diszo [ABC]20-30, TOTO(I+1)
# Gray out  all the fields of mask with the abbreviation ABC.
Diszo [ABC]

Description

Diszo is used to gray out all or part of the fields in a mask, for example further to a Actzo.

Diszo is used for fields declared as being enterable in the mask. These fields can no more be entered.

When fields are made unavailable again via Diszo, the order to gray the elements always derives from the entry ranks and the position of the fields on the screen. As a consequence if this order to gray out fields needs to be modified, it is necessary to use several Diszo statements.

Similarly, when giving an interval of the fields to be grayed out, it is the entry order that is considered to determine which are the fields in the interval.

A grid can be fully or only partially grayed out. The syntaxes are the same:

Diszo [M]NBLIG Where NBLIG is the grid bottom variable

or Diszo [M]xx Where xx is the rank

Diszo [M]FIELD Where FIELD is a column name, grays outs the column

Diszo [M]FIELD(nolign-1) Where FIELD is a column name and nolignthe line number, grays out a cell.

In a grid, a grayed-out field appears in a grey font. If the field has a color attribute via pcolor, its color is kept. On fields other than the grid bottom variable, the Diszo doe not enables the on focus nor the contextual menu.

Notes

Diszo positions the screen as valid. The field checks will not be carried out. Diszo on rank(s) or field(s) does not modify the validity status of the mask.
