A large number of common tasks are available in the form of built-in functions, subroutines, and pseudovariables. When you use them, you can write less code more quickly with greater reliability.
The built-in functions, subroutines, and pseudovariables are listed in alphabetic order in this chapter. In general, each description has the following format:
The abbreviations for built-in functions have separate declarations (explicit or contextual) and name scopes. In the following example:
dcl (Dim, Dimension) builtin;
is not a multiple declaration, and
dcl Binary file; X = Bin (var, 6,3);
is valid even though Bin is an abbreviation of the Binary built-in function.
