<br />OlJllO'L <br /> <br />1. Execute OPEN40 to create two blank direct access files (T APEll.DIR and <br />TAPEI2,DlR), <br />2. Execute MHYDRO's UPDATE option to fill TAPEI1.DIR and <br />TAPE 12,DIR with data, <br />3. Execute MHYDRO's CRSM option to build an input file to CRSM <br />(TAPE3), <br /> <br />. MHYDRO contains many functions (create data for CRSM, create Punch output, <br />perform statistical analyses, etc,), To reduce the time required for the porting, <br />only the following portions of MHYDRO were checked: <br /> <br />1. UTILITY, which puts data into files IAPEI1.DIR and TAPEI2.DIR. <br />2, CRSM, which creates data for CRSM, <br />3. PUNCH, which creates an output file for review and checking, <br /> <br />. The approach used to replace the mass storage routines with standard read and <br />write statements was adopted from the DWB version, As part of this conversion, <br />the DWB changed the station ID by adding 5, No explanation for adding 5 was <br />identified, therefore it was not done by this porting, <br /> <br />. Future refinements to the ported MHYDRO which may be useful include the <br />following: <br /> <br />1. Complete conversion checking of other portions of the program, such as <br />PUNCH and the STATS subroutines. <br /> <br />2, Incorporate the functionality of the utility OPEN40 within MHYDRO <br />itself, <br /> <br />Conclusions <br /> <br />MHYDRO has been converted from the USBR's Cyber to a PC, Results produced <br />by MHYDRO directly and those used by CRSM appear to be the same as those <br />produced by the Cyber. <br /> <br />fn=\crss\word\mm 122993,doc <br /> <br />5 <br />
