ForCase Statement

Format

forcase dictionary_name ʃwhere conditionʅ do
// statements
endfor;

Description

The forcase statement executes one or more statements repeatedly within a loop for each case in a file opened as external dictionary dictionary_name. An optional logical condition, referencing items in the external dictionary, can be supplied to restrict the cases processed by the loop.

It is possible, by specifying dictionary access parameters after the dictionary name, to limit the cases that the forcase loop processes.

Example

numeric incomplete_households;

forcase CENSUS_DICT where INTERVIEW_STATUS = 3 do
inc(incomplete_households);
endfor;
