@madisongaw wrote: Tabs? DLM='09'x? Once upon a time there were machines called "typewriters". These were mechanical devices with a keyboard and when keys were pressed an arm moved and hit an ink saturated cloth ribbon. The arm had a letter shape cast into it and when it struck the ribbon which was next to a piece of paper the ink was transferred, creating typed letters on the paper. As the keys were pressed a carriage holding the paper moved so that all the letters were spaced apart. Because there are times that you want to align things on paper, ie create "tables", there were mechanical stops that were eventually called "tab stops" or tabs.    Years later a similar system was used to send messages by radio but the letters were turned into electronic pulses with numeric equivalents. '09'x is a hex number that references the numeric equivalent for the mechanical tab stop. A change in slightly more modern items is that the "tab" will typically advance to column that is a multiple of some setting, such as every 5 characters, in an electronic file. So depending on what you view the file will you may get some columns aligned when the previous chunk of information ends prior to whatever multiple that may be. If the length of the previous data element exactly corresponds to the tab number of character setting there may appear to be no space, but actually there is a character, the "tab", that just is not displayed.   Tab-delimited, or a tab character between every data element, is a moderately common way to provide data. ...
