There are many ways to draw text in a window in an OS/2 application. The simplest way is to use the WinDrawText function, which draws a single line of text in a specified rectangle, using a variety of alignment methods.

WinDrawText allows you to set a flag so that the function does not draw any text; instead, the function returns the number of characters in the string that will fit in the specified rectangle. For a section of running text, an application can alternate between computation and calls to WinDrawText to draw successive lines of text. When performing this kind of repetitive operation, you can set the DT_WORDBREAK flag in the WinDrawText function to put line breaks on word boundaries rather than between arbitrary characters.
