Editing Integer BASIC (section)

===Debugging===
As in most BASICs, programs were started with the {{code|RUN}} command, and as was common, could be directed at a particular line number like {{code|RUN 300}}.{{sfn|Raskin|1978|p=100}} Execution could be stopped at any time using {{key press|Ctrl|C}}{{sfn|Raskin|1978|p=15}} and then restarted with {{code|CON}}tinue, as opposed to the more typical {{code|CONT}}.{{sfn|Raskin|1978|p=52}}

For step-by-step execution, the {{code|TRACE}} instruction could be used at the command prompt or placed within the program itself. When it was turned on, line numbers were printed out for each line the program visited. The feature could be turned off again with {{code|NOTRACE}}.{{sfn|Raskin|1978|p=107}}

A somewhat unusual feature was the {{code|DSP}} (for "display") command. When encountered in a program, from that point on any ''changes'' to a variable's value would be displayed. For instance, {{code|DSP X}} would display the value of X every time it changed, along with the line number where the change occurred.{{sfn|Raskin|1978|pp=100,101}} As with TRACE, DSP was turned off with {{code|NODSP}}.{{sfn|Helmers|1978|p=24}}
