INF/HLP (OS/2)

INF and HLP are two variants of a help file format associated with OS/2's "Information Presentation Facility", and used by some OS/2 applications. Files can be viewed with an OS/2 app named VIEW.EXE.

INF and HLP files are usually created by compiling a source format called IPF.

Identification
Files begin with ASCII "", followed (usually?) by "".

The next byte is (usually?) for INF, or  for HLP.
