APPEND - append text to file.

$*$Append filename

begins writing text to the specified file. This output is appended to the current contents of the file. The text to be written starts with the line after the $*$Append directive and ends at an appropriate line of the form

$*$EndData filename

where the "filename" is the same as the one on the $*$Append directive. Each line in this block of text is expanded and the result is written to "filename". An $*$EndData line without a filename ends any preceding $*$Append directive.

$*$Append filename :line

appends the given "line" to the specified file. With this format, you do not use $*$EndData.
