NoteThis command is defined in a header file and will be preprocessed by the X# preprocessor to a function call. If you disable the standard header (-nostddefs) files then this command will not be available. If you tell the compiler to use a different standard header file (-stddef ) then this command may also be not available


Tally the number of records from the current work area that match the specified record scope and condition, and place the result in the specified variable.


COUNT TO <idVar> [<Scope>] [WHILE <lCondition>] [FOR <lCondition>]


TO <idVar>The variable or field that holds the COUNT result.  A variable that either does not exist or is invisible is created as a private variable.


<Scope>The portion of the current database file to process.  The default is all visible records. Scope is one or more clauses of:
[NEXT <NEXT>]        Optionally specifies the number of records to process starting
               with the first record of the source file.
[RECORD <rec>]        An optional record ID If specified, the processing begins
               with this data record in the source file.
[<rest:REST>]        The option REST specifies whether records are sequentially
               searched only from the current up to the last record.
               If a condition is specified, the option ALL is the default value.
[ALL]                The option ALL specifies that all records from the source file are imported.
               This is the default setting.


WHILE <lCondition>A condition that each visible record within the scope must meet, starting with the current record.  As soon as the while condition fails, the process terminates.  If no <Scope> is specified, having a while condition changes the default scope to the rest of the visible records in the file.


FOR <lCondition>A condition that each visible record within the scope must meet in order to be processed.  If a record does not meet the specified condition, it is ignored and the next visible record is processed.  If no <Scope> or WHILE clause is specified, having a for condition changes the default scope to all visible records.



This example demonstrates a COUNT using a particular Branch in SALES.DBF:


USE sales NEW
COUNT TO nBranchCnt FOR Branch = 100
? nBranchCnt               // Result:  4


The next example tallies the number of records in SALES.DBF whose Branch has the value of 100 and assigns the result to the Count field in BRANCH.DBF for branch 100:


USE branch INDEX branch NEW
SEEK 100
USE sales INDEX salesbranch NEW
SEEK 100
COUNT TO Branch->Count WHILE Sales->Branch = 100
