ddlFindCalc() - isolate records in a collection using Calc-Object ddlFindCalc() - isolate records in a collection using Calc-Object

Prototype:

   void ddlFindCalc(
      CONTROL *ctl,
      char *OptnStr,
      char *ArgList);

Permitted values in OptnStr:

   /Cn - return first n values only

Form of ArgList:
Case 1: <cx> [<dgname>] <expression>
Case 2: <cx> [<dgname>] <cx> AND <expression>

Description:

First, ddlFindCalc() creates the Calc-Object:
       IF <expression>
          SELECT <cx>
       ENDIF
Then, in case 1:
      • Clears the collection <cx> [<table-name>];
      • Performs the Calc-Object against all records in <table-name>; or, if <table-name> is not specified,
         against all records in all tables
In case 2:
      • Copies the collection <cx> [<table-name>]; to a tempory collection
      • Clears the collection <cx> [<table-name>];
      • Performs the Calc-Object against all records in the temporary collection;

Value returned in Control.Ans1:

Control.Ans1	Total number of records selected
Control.Ans2	If the /Cn option was used, this is the number of records selected before the /Cnnn limit was applied; else, it is a duplicate of Control.Ans1
