Concatenation of .INF files is useful when you have a large amount of information that cannot be compiled as one file that fits on a diskette. If you want to concatenate files, you must use the res= attribute for window identifiers.

After you have created your .INF files, use the SET command to set an environment variable equal to a string that consists of the .INF file names, for example:

SET PROGREF=PRINTRO.INF+PRCP.INF+PRWIN.INF+PRDATA.INF

When you specify the environment value as a parameter to the VIEW program, VIEW displays the online information. Headings from the different files are displayed in the contents window in the order the files are concatenated for the environment variable.
