LCRCK.ASM was written as a replacement for LCRCK.C (originally
written 1-30-83 by myself). It is somewhat faster and quite a
bit smaller than the C version.

LCRCK, in the true spirit of all such RCPM programs, processes only
one file at a time. It can be used to compute the "CRC" or Cyclic
Redundancy Check of a member file inside a library. the resulting
four-digit hex number will be the same as the one returned by
CRCK44.COM run on the identical standalone file. Therefore, LCRCK
can be used to verify the integrity of an individual member file
transferred via the XMODEM L command.

The program can be configured for maximum drive and user without
reassembly, which is of advantage to those who do not have M80.
At location 103, insert the maximum drive +1, i.e. A=2, B=3.
At location 104, insert the maximum user number +1.

The program uses the CRCK2 routines in SYSLIB. If the CRC2 calls are
replaced with CRC calls to SYSLIB, the value returned is the same as
the one computed and placed into the LBR directory by LU300.

For those using the CHEK program instead of CRCK, a version of
LCHEK is forthcoming.
