Hi, Aia.
Yes, I noted that. His title was What is the meaning the $ special character?
He also asked ...explain to me how it's categorized and it's extract [sic] definition?
He did not restrict the meaning to any special instance.
I appreciate that he used Google, but I think he may not have had enough time to internalize the information. I know that I don't always understand something just after I read it.
For example from the Wikipedia article: In most shell scripting languages, $ is used for interpolating environment variables, special variables ... -- it seems hard to imagine an alternate definition.
Thanks for the comment, it's always useful to have feedback and more than one set of dispassionate eyes looking over things ... cheers, drl

NAME
PX_timestamp2string -- Convert paradox timestamp into formated string
SYNOPSIS
#include <paradox.h>
char * PX_timestamp2string(pxdoc_t *pxdoc, double timestamp, const char *format)
DESCRIPTION
Creates a string representation of a paradox timestamp as specified in the parameter format. The timestamp must be either retrieved with
PX_get_data_double(3) after calling PX_get_record(3) or by simply using the double value in the pxval_t struct as returned by
PX_retrieve_record(3). A timestamp contains both time and date information. The format string contains chars which stand for certain values
of the date/time. The following table lists all available characters with a meaning. All other characters are being copied unmodified to
the output string. If a special character shall not be interpreted it must be preceded with a backslash.
