126 /* This routine will accept a list of one or more double precision */
127 /* numbers which it will encode into equivalent text strings and */
128 /* write to the current position in a text file. The current */
129 /* position in a file is defined to be the text line immediately */
130 /* following the last text line that was written or read. The */
131 /* encoded d.p. numbers are written to the output text file as */
132 /* quoted character strings so that a Fortran list directed read may */
133 /* be used to read the encoded values, rather than a formatted read */
134 /* with the format specifier FMT = '(A)'. */
135
136 /* This routine is one of a pair of routines which are used to */
137 /* encode and decode d.p. numbers: */
138
139 /* WRENCD -- Encode and write d.p. numbers to a file. */
140 /* RDENCD -- Read and decode d.p. numbers from a file. */
141
142 /* The encoding/decoding of d.p.numbers is performed to provide a */
143 /* portable means for transferring data values. */
144
145 /* Currently the text string produced will be in a base 16 */
146 /* ``scientific notation.'' This format retains the full precision */
147 /* available for d.p. numbers on any given computer architecture. */
148 /* See DP2HX.FOR and HX2DP.FOR for details. */

150 /* $ Examples */

152 /* Please note that the output format in the examples is not */
153 /* intended to be exactly identical with the output format of this */
154 /* routine in actual use. The output format used in the examples is */
155 /* intended to aid in the understanding of how this routine works. */
156 /* It is NOT intended to be a specification of the output format for */
157 /* this routine. */
158
159 /* Let */
160
161 /* UNIT be the Fortran logical unit of a previously opened */
162 /* text file. */
163
164 /* N = 100 */
165
166 /* DATA(I) = DBLE(I), I = 1,N */
167
168 /* Then, the subroutine call */
169
170 /* CALL WRENCD( UNIT, N, DATA ) */
171
172 /* will write the first 100 integers as encoded d.p. numbers to the */
173 /* output text file attached to UNIT, beginning at the current */
174 /* position in the output file, which is marked by an arrow, '-->'. */
175 /* The resulting output will look something like the following: */
