CDS057
The purpose of this routine is to read, print, or convert
VDT Formats. It is not typically called within an application program. It can be
used however to display the specified VDT format.
Called program CDS257 is now used to print window
text created with CDS069 using the W{} option. However
to retain compatibility, CDS057 will call CDS257 when
called referencing a file other than a VDT format file.
In its most complete form, CDS057 is called using the following variables:
