Built-In Environment Objects

Rexx provides environment objects that all programs can use. To access these built-in objects, you use their environment symbols whose first character is a period ( .).

.line The.lineenvironment symbol returns the line number of the current instruction being executed. If the current instruction is defined within an INTERPRET instruction, the value returned is the line number of INTERPRET instruction.
.rs .rsis set to the return status from any executed command, including those submitted with the ADDRESS instruction. The.rsenvironment symbol has a value of-1when a command returns a FAILURE condition, a value of1when a command returns an ERROR condition, and a value of0when a command indicates successful completion. The value of.rsis also available after trapping the ERROR or FAILURE condition.
Note Tracing interactively does not change the value of.rs. The initial value of.rsis0.
