VAX/SGI -> IBM RISC/6000 source format problem with FORTRAN code

[hoberoi at eagle.wesleyan.edu]

I am porting several programs that compile on SGI and vaxen to the IBM
RISC/6000.

problem : the source is tab delimited and extends over 72 columns and will
therefore not be accepted by xlf. Replacing tabs with spaces will not work as,
the fixed format for xlf will ignore colums beyond 72. Free format source on 
the otherhand requires a "-"(!!) at end of line for long lines and will not 
accept either the tab delimited stuff or continuation lines (ie column 6 etc ).

anyone worked this out ?!!

himansu.

PS: WHY use a confusing "-" sign to indicate a continuation line a "\" would
have been more appropriate here.
