The IPF compiler is invoked using the IPFC command, as follows:
IPFC SOURCE.IPF /X /W3 >ERRORS.TXT
The above command invokes the IPF compiler with the input file SOURCE.IPF. The /X parameter instructs the compiler to produce a cross-reference listing for all headings, diagrams, etc. The /Wn command specifies the level of error-reporting to be performed; valid levels are 1 (/W1) to 3 (/W3). The final parameter pipes any error messages to the file ERRORS.TXT in order that they may be examined later. The IPFC command is fully documented in the IBM OS/2 Version 2.0 Information Presentation Reference.
When creating online documentation that will function in a stand-alone format rather than as help associated with an application, the /INF parameter is specified. This causes the IPF compiler to search for source files with the INF extension, and to format the output for use with the online viewing utility VIEW.EXE.
