Example:
Returns the number of times the string substring appears within the string text. The result is an
integer. If there is no match, 0 is returned
substringcount ( 'abcdefgcdxyz', 'cd' ) returns 2
applycodepage(text, codepage)
Applies a different codepage to the field or text stated in the expression. The codepage must be in
number format.

Mapping Functions
The ApplyMap function is used for mapping any expression to a previously loaded mapping table. The syntax
is:
applymap('mapname', expr [ , defaultexpr ] )
where:
mapname is the name of a mapping table that has previously been created through the mapping load or the
mapping select statement (see Mapping (page 253)). Its name must be enclosed by single, straight Quotation
Marks (page 281).
expr is the expression, the result of which should be mapped.
defaultexpr is an optional expression which will be used as a default mapping value if the mapping table
does not contain a matching value for expr. If no default value is given, the value of expr will be returned as
is.
Examples:
// Assume the following mapping table:
map1:
mapping load * inline [
x, y
1, one
2, two
3, three ] ;
ApplyMap ('map1', 2 ) returns ' two'
ApplyMap ('map1', 4 ) returns 4
ApplyMap ('map1', 5, 'xxx') returns 'xxx'
ApplyMap ('map1', 1, 'xxx') returns 'one'
ApplyMap ('map1', 5, null( ) ) returns NULL
ApplyMap ('map1', 3, null( ) ) returns 'three'
The MapSubstring function is used to map parts of any expression to a previously loaded mapping table.
The mapping is case sensitive and non-iterative and substrings are mapped from left to right. The syntax is:
mapsubstring('mapname', expr)
