>Just a WAG but there might be a port blocked - perhaps refusing a ping back or something. If you turn off your firewall will it work?

No, the code works for the older standard going through the same port.

Here is what I discovered so far.....

.....
I rewrote the code as below...

IF !DIRECTORY(gcPath + "\Surescripts")
	MKDIR gcPath + "\Surescripts"
ENDIF
lcPath = gcPath + "\Surescripts\"
lcFile = lcPath + PADL(ALLTRIM(ss_io.message_ref),7,"0") + PADL(ALLTRIM(ss_io.refill_no),2,"0") + ".REQ"
lnHandle = FCREATE(lcFile)
IF lnHandle > 0
	*TMN 03/16/09
	*TMT 04/19/13 Modified for v10.6
	FWRITE(lnHandle,lcText,5979)	&& Uses FWRITE instead of FPUTS cuz no LF CR are needed
	*FWRITE(lnHandle,lcText,5416)	&& Uses FWRITE instead of FPUTS cuz no LF CR are needed
	*FWRITE(lnHandle,lcText,5259)	&& Uses FWRITE instead of FPUTS cuz no LF CR are needed
	*TMN 03/16/09
	FCLOSE(lnHandle)

*!*		lcEXE = gcPath + "\WssPost.exe" + " " + ALLTRIM(interface.ss_ip) + ":" + ALLTRIM(STR(interface.ss_port)) + " " + ALLTRIM(pharmacy_config.nabp) + " " + lcFile
*!*		RUN /N2 &lcEXE
*TMT 04/26/13 Change from RUN to ShellExecute because the 10.6 was throwing an exception error when 4.2 did not....
*!*		lcEXE = gcPath + "\WssPost.exe" + " " + ALLTRIM(interface.ss_ip) + ":" + ALLTRIM(STR(interface.ss_port)) + " " + ALLTRIM(pharmacy_config.nabp) + " " + lcFile
*!*		RUN /N2 &lcEXE

	DECLARE LONG ShellExecute in "shell32.dll" long hwnd, string lpszOp, ;
	             	string lpszFile, string lpszParams, ;
	                string lpszDir, long nShowCmd	
	
	lcEXE = gcPath + "\WssPost.exe" 
	lcParms = ALLTRIM(interface.ss_ip) + ":" + ALLTRIM(STR(interface.ss_port)) + " " + ALLTRIM(pharmacy_config.nabp) + " " + lcFile
	ShellExecute(0,"open",lcExe,lcParms,lcPath,7)

ELSE
	MESSAGEBOX(translatewrd("Cannot create EZ e-Script text file"),16,translatewrd("EZ e-Script Create File"))
ENDIF

.... and I got the SAME ERROR result !!!

So, I figured, what is different? Originally, this code worked when I was using it with the older standard which created the textfile lcFile. This file was 5416 bytes long.

In this code, the textfile is longer, due to the new standard. The file is now 5979 bytes long.

So, the shorter file works, but the longer textfile does not. It causes the error.

So, I traced the code back to this point, and after the LONGER text file was created, I erased it and replaced it with the shorter file, but with the same name as the LONGER file, and ran it on through. NO ERROR. So, something about the length of the textfile is the problem.

Your thoughts?
