WHLCHK Ver 1.1 10/27/84 %%%%%%%%%%% corrected spelling on output message....nlb %%%%%%%%%%% For ZCPR users, here is WHLCHK.COM. This program will modify any .COM program so that it first checks for the ZCPR3 wheel byte, and if not set, will terminate with the message PROGRAM ACCESS DENIED.... Syntax: WHLCHK filenm[.COM] You need only run WHLCHK one time, it reads in the named COM program, modifies it to check for the wheel byte, and saves it back to disk. You should first save your original program....there is no UNWHLCHK.COM, in case you ever change your mind!!!! Zcpr2 users should change the wheel byte location.... Norman Beeler
