Re: converting string to a numeric

[Tarlochan Bimbra <bimbra@xxxxxxxxxx>]

Chris,

I have used C's atoll function which converts an alpha string data to a 
long long integer.
See if this help with your task.

H bnddir('QC2LE') 
D charToNum       pr            20i 0 extproc('atoll') 
D   string                        *   value options(*string) 
 * 
D DateField       s               d   datfmt(*iso) inz(*sys) 
D USADate         s              8s 0 
 /free 
     USADate = charToNum(%char(DateField:*USA0)); 
     *inlr = *on; 
 /end-free

converting  string to a numeric







Hello,
I need to know how to convert a string to a numeric. The following works
fine.
 
d thedate         s               d 
 d startdate       s              7a 
 
 
  /free 
     thedate = %date(*date);

     startdate = '1' + %subst(%char(thedate):3:2) + 
      %subst(%char(thedate):6:2) + %subst(%char(thedate):9:2); 
  /end-free 
 c                   seton                                        lr
 
and I end up with a string that represents a date in the form CYYMMDD.
 But what I really need is a number in that format. Something like
 
 d thedate         s               d 
 d startdate       s              7a 
 
 
  /free 
     thedate = %date(*date);

     startdate = %ConvertThisSuckerToaNumber('1' +
%subst(%char(thedate):3:2) + 
      %subst(%char(thedate):6:2) + %subst(%char(thedate):9:2)); 
  /end-free 
 c                   seton                                        lr
 
I looked through the reference manual and found %dec but that does not 
seem
to do the trick. When I try to use that I get
 
*RNF0327 30     10 001000  The first parameter for %DEC or %DECH is not
valid.
 
 
Anyone have any good ideas on this one?
 
Thank You,
Chris Payne
