Interface block data types

Arthur Olin Sat 07/Aug 99

When an interface block is used to test arguments passed to an f77-style routine

the f77-style data declarations should be used. This is best done by cutting and pasting from the

f77 routine. On the DEC Alpha I tried using the f90-style declaration INTEGER::IBANK

for an array passed to YBOS routines where it was declared INTEGER*4. There was

no compilation error, but the array had different values within the YBOS routine than it

had in the calling routine. The problem was not present when the interface block

declaration was INTEGER*4 IBANK or when the interface block was omitted.
