Nature of problem:
ASYPRO is a preprocessor for the program ASYPCK.

Solution method:
ASYPRO reads two cards. The first specifies files IT1, IT2, IT3 and print level. File IT1 contains the unprocessed program ASYPCK and file IT2 is used for scratch storage. The processed FORTRAN program ASYPCK is written on the file IT3. THe second card specifies three basic dimension numbers for ASYPCK and a parameter MACH, which controls the activation or de-activation of machine-dependent statements in ASYPCK. ASYPRO computes subsidiary dimension numbers and, depending on the value of MACH, instructions for insertion or deletion of timing routines and the optional insertion of CDC PROGRAM cards. ASYPRO calls a modified version of the University College London String Replacement Program.

Restrictions:
ASYPRO uses one character not in the standard FORTRAN character set. In CDC Standard Hollerith this is a 5,8-hole punch and is printed on CDC machines as "<=".

Running time:
1.6 s on the CDC 7600 at the University of London Computer Centre for the processing of 3872 cards on file IT1.
