WordStar was carried out before the text to be formatted - unlike many other word processors where the formatting of a paragraph is 'buried' within the usually hidden paragraph marker at the end of the paragraph. This latter method leaves the user unclear where formatting starts. In normal editing, WordStar hides formatting markers but these are easily displayed with ^OD command. Formatting information is then displayed in the normal text area displacing the actual text. It nonetheless made it absolutely clear where formatting started and finished. Page and section formatting was handled differently by the addition of formatting lines. A formatting line was indicated by the line starting with a full stop. Some third-party WordStar books called formatting lines "dot commands". A few examples: .lh (line height) .lm (left margin) .rm (right margin) - each of which was followed by a number. The number was assumed to be points (pt) but could be easily modified to inches or mm by the addition of " or mm after the number. .lm and .rm were never equal as both values were from the left hand edge of the page. Setting .rm to 0 made text lines infinitely long. Margins could also be set either absolutely or relatively (by preceding the value with either - or +) when setting the value. If any invalid formatting commands are encountered, when printing WordStar (version 3.3 at least) will ignore the line (all text until the next carriage return terminating the line). This could confuse novice users who unintentionally began a line with a decimal point (same as period or dot character) and WordStar would not print the line. For instance, a line reading: ".05 percent text text text..." would not appear in the printout though the document would continue on the printout without any error reported. WordStar 2000 added few new commands, but completely rewrote the user interface, using simple English-language mnemonics (so the command to remove a word, which had been ^T in WordStar, became ^RW in WordStar 2000; the command to remove the text from the rest of the line to the right of the cursor changed from ^QY to ^RR). However, many in WordStar's large installed user based were happy with the original WordStar interface, and did not consider the changes to be improvements. Although WordStar 2000 was meant as the successor to WordStar, it never gained substantial market share. The original
