the - in front of EOF tells the here doc to ignore any leading whitespace to allow it to be indented for easy looking code. There is no problem with the here document as I use this syntax on numrous other occassions successfully. The problem only occurs when the perl script "program" calls a subscript

dgr2file
DGR2FILE(1) DGR executables DGR2FILE(1)
NAME
dgr2file - DGR reception test program
SYNOPSIS
dgr2file
DESCRIPTION
dgr2file uses DGR to receive multiple copies of the text of a file transmitted by file2dgr, writing each copy of the file to the current
working directory. The name of each file written by dgr2file is file_copy_cycleNbr, where cycleNbr is initially zero and is increased by 1
every time dgr2file closes the file it is currently writing and opens a new one.
Upon receiving a DGR datagram from file2dgr, dgr2file extracts the content of the datagram (either a line of text from the file that is
being transmitted by file2dgr or else an EOF string indicating the end of that file). It appends each extracted line of text to the local
copy of that file that dgr2file is currently writing. When the extracted datagram content is an EOF string (the ASCII text "*** End of the
file ***"), dgr2file closes the file it is writing, increments cycleNbr, opens a new copy of the file for writing, and prints the message
"working on cycle cycleNbr."
dgr2file always receives datagrams at port 2101.
EXIT STATUS
0 dgr2file has terminated.
FILES
No configuration files are needed.
ENVIRONMENT
No environment variables apply.
