4.2.7 The Current Trapped Condition The interpreter maintains a data structure called the current trapped condition. It contains information relating the most recent condition trapped on this or higher procedure level. The current trapped condition is normally inherited by subroutines and functions, and restored after return from these. · When trapped by method SIGNAL the current trapped condition of the current procedure level is set to information describing the condition trapped. · When trapped by method CALL, the current trapped condition at the procedure level which the trap occurred at, is not changed. Instead, the current trapped condition in the condition handler is set to information describing the condition. The information stored in the current trapped condition can be retrieved by the built-in function CONDITION(). The syntax format of this function is: CONDITION(option) where option is an option string of which only the first character matters. The valid options are: Condition name, Description, Instruction and State. These will return: the name of the current trapped condition; the descriptive text; the method; and the current state of the condition, respectively. The default option is Instruction. See the documentation on the built-in functions. See also the description of each condition below. Note that the State option do not return the state at the time when the condition was raised or the trap was triggered. It returns the current state of the trap, and may change during execution. The other information in the current trapped condition may only change when a new condition is trapped at return from subroutines.
