.SH "DESCRIPTION" 
.PP 
Converts a data field as it stored in the database file into 
a bcd string. The string will not be longer than 20 chars including 
the final 0. It contains only the characters `+', `\-', `0-9', and `.'. 
You should use this function 
instead of accessing the data directly. 
.PP 
\fBdata\fP points to the start of the data field in the 
record. It must be calculated by summing up all field length before 
the field to operate on and add it to the base pointer of the 
record. \fBlen\fP is the number of digits after the decimal 
point. 
.PP 
The function allocates memory for the string returned in 
\fB*value\fP. This memory has to be freed by the application.
