Hi all,

I have written a procedure which controls the writing of a batch file and executes it through executescript
here is the command:
executeScriptText/Z/B "C:\\hysplit4\\cluster\\working\\batch_CCONTROL.bat"

Although the batch with this command is launched on my computer, it is not the case on other PCs.... is there any known reason why this should happen?

some hints:
- tried to run Igor in Administrator mode, but doesn't work.
- removed the /Z flag, but didn't get an error message.
- here is the function that writes the batch file

Function CCONTROL_batch()
	SetDataFolder root:ZeFir:data2use:
	NVAR/Z Hours2Cluster=root:ZeFir:Traj_A:variables:Hours2Cluster
	NVAR/Z SkipTraj=root:ZeFir:Traj_A:variables:SkipTraj
	NVAR/Z SkipEndpoints=root:ZeFir:Traj_A:variables:SkipEndpoints
	string Batch_str=""
	Batch_str+="cd C:/hysplit4/cluster/working/;"
	Batch_str+="echo "+num2str(Hours2Cluster)+"  >>CCONTROL;"
	Batch_str+="echo "+num2str(SkipTraj)+"  >>CCONTROL;"
	Batch_str+="echo "+num2str(SkipEndpoints)+"  >>CCONTROL;"
	Batch_str+="echo C:/hysplit4/cluster/working/  >>CCONTROL;"
	Batch_str+="echo 0  >>CCONTROL;"
	Make/T/O/N=(ItemsInList(batch_str, ";")) batch_txt
	batch_txt = StringFromList(p, batch_str, ";")
	Newpath/O/Q BatchPath, "C:hysplit4:cluster:working:"
	sleep/s 1
	Save/T/G/O/M="\r\n"/P=BatchPath Batch_txt as "batch_CCONTROL.bat"
	Killwaves batch_txt
End Function

I recently found that you need to use /C with cmd.exe to execute a DOS batch file. This led me to add this example to the Igor 7.04 help:

//	Windows: Execute a DOS command and get output, if any
// ExecuteDOSCommand(command, maxSecondsToWait)
// Executes a DOS command and returns any output text as the function result.
// Returns "" if the DOS command returns no text.
// maxSecondsToWait is the maximum number of seconds to wait for DOS to finish
// the command. If it takes longer than that, an error is generated.
// This function creates files in the Igor Pro User Folder:
//		igorBatch.bat	Holds command that DOS is to execute
//		igorBatchOutput.txt	Holds output generated by DOS command, if any
// Example:
//		Print ExecuteDOSCommand("echo %PATH%", 3)
Function/S ExecuteDOSCommand(command, maxSecondsToWait)
	String command	// e.g., "echo %PATH%"
	Variable maxSecondsToWait	// Error if DOS takes longer than this
	String quoteStr = "\""
	// Get path to batch file in "Igor Pro User Files"
	String dirPath = SpecialDirPath("Igor Pro User Files", 0, 0, 0)
	dirPath = ParseFilePath(5, dirPath, "\\", 0, 0)	// Convert to Windows path
	String batchFilePath = dirPath + "igorBatch.bat"
	String batchOutputFilePath = dirPath + "igorBatchOutput.txt"
	DeleteFile/Z batchOutputFilePath
	// Write DOS command to batch file
	String dosCommand = command + " > " + quoteStr + batchOutputFilePath + quoteStr
	Variable refNum
	Open refNum as batchFilePath
	FBinWrite refNum, dosCommand
	Close refNum
	// Execute batch file
	// The DOS command must complete in the number of seconds specified via /W
	// /C means cmd.exe quits after executing the command
	String text
	sprintf text, "cmd.exe /C \"%s\"", batchFilePath
	ExecuteScriptText/W=(maxSecondsToWait) text
	// Get output
	String result = ""
	Open/R/Z refNum as batchOutputFilePath
	if (V_flag != 0)
		result = ""
		// result = "<No output was generated by batch file>"	// For debugging
		// Read contents of batch file into string
		FStatus refNum
		Variable numBytesInFile = V_logEOF
		result = PadString("", numBytesInFile, 0x20)
		FBinRead refNum, result
		Close refNum
	return result
