I have to compile some sources which were written for MF and IBM
compilers with hp cobol compiler but i'm not an experienced cobol
programmer so i need a little bit of help.

The questions are:
1. Does hp cobol compiler know about hexa literals? For example MF
recognize
X"4142" ("AB") .
2. Is it possible to create  copy libraries from  POSIX files (i.e files
edited with vi)? I tried adding such files to a copy library with
COBEDIT.PUB.SYS but when i used copy statement to include modules from
this library in a source code i got tones of compiling errors from this
modules even if everything was ok when i used $INCLUDE .

Thanks!
