Help for GTIGEOLO

PURPOSE:
1) Parses a particular string for northing easting coordinates.

"ddmmssNdddmmssEddmmssNdddmmssEddmmssNdddmmssEddmmssNdddmmssE"

where dd or ddd is degrees, mm is minutes, and ss is
seconds.  The N and E are characters identifying north
or east.  The values are computed as

  dd+mm/60+ss/3600

and returned in tcl variables.

The n1 and e1 refers the first coordinates in the string
and n4, e4 refers to the last coordinates in the string.

2) Accepts input of n1inp, n2inp, ... , n4inp, e1inp,
e2inp, ... , e4inp, converts the inputs from degrees
to minutes and outputs a string in the form:

"ddmmssNdddmmssEddmmssNdddmmssEddmmssNdddmmssEddmmssNdddmmssE"

EXECUTION:

Examples

gtigeolo
 inp="343214N1105258E343208N1110441E342220N1110443E342222N1105251E"
 n1=tclreal1 n2=tclreal2 n3=tclreal3 n4=tclreal4 e1=tclreal5
 e2=tclreal6 e3=tclreal7 e4=tclreal8

          returns the north and east values into the
          tcl variables.

gtigeolo n1inp=-3.437277777778e+01 n2inp=-3.453555555556e+01
         n3inp=-3.933333333333e+01 n4inp=-3.950000000000e+01 
         e1inp=1.108808333333e+02 e2inp=1.110780555556e+02
         e3inp=8.433333333333e+01 e4inp=8.450000000000e+01
         out=tclstr

          returns the degrees minutes seconds into the
          tclstr string variables.

OPERATION:
gtigeolo does not use VICAR I/O.

 TIMING: 

As fast as C can parse a string.
