XSTEP monitor command XSTEP monitor command Syntax XSTEP task program (param_list), cycles, step Function Execute a single step of a program. Usage Considerations XSTEP can be used to single-step any of the system program tasks, independent of the execution status of other system tasks. Parameters task Optional integer that specifies which system program task is to be executed. If no task number is specified: task 0 is assumed. program Optional name of the application program to be executed. 1 param_list Optional parameter list for the program.
(See the description of the EXECUTE command and instruction for details.) cycles Optional real value, variable, or expression (interpreted as an integer) that specifies the number of program execution cycles to be performed. (See the description of the EXECUTE command and instruction for details.) step Optional real value, variable, or expression (interpreted as an integer) that specifies the step at which program execution is to begin. Details The XSTEP command can be used to execute an application program one step at a time. This is frequently useful while a program is being developed and program errors are being found and corrected. Three aspects of program execution must be kept in mind:
1. The system program task that is to be utilized 2. The program that is to be executed 3. Program execution is stopped after one instruction. eV+Operating System Reference Guide, 2.x,18321-000 Rev A Page 192
