Sub (function)
Subtracts one expression from another. This is the functional equivalent of the - operator.
Syntax
sub( expression, expression2 ) integer, measure, currency value
Arguments
expression1, expression2
Integer, measure or currency values. Both expressions must be the same type. The returned value is set according to the type
of the parameters.
Code Sample Example
Example 1 and Example 2 illustrates both ways of subtracting numbers.
Example 1
show(inttostr(2-2))
Example 2
show(floattostr(sub(4.7,2.1)))
SubRecCount (function)
Returns the number of records per data page. Since data pages can hold a variable number of records, this value may change
whenever you skip through data pages. Every data page always has at least one child, otherwise it wouldn't be stored in the
database. Subreccount can return 0 only if the emulation is set to something other than database mode, or if the converted
database is invalid. This function is only useful in database emulation mode.
Syntax
subreccount integer value
