Robo-FTP User's Guide > Script Programming > Script Commands > All Script Commands > IFSIZE - Conditional branch upon file size comparison

Form 1

Syntax:	IFSIZE	[ cond ] GOTO [ label ]
Arguments:	[ cond ]	Variable or string defining a size condition to test against the internal %comparesize variable.
	[ label ]	A valid label within the current script file which is branched to if the specified file exists.
Options:	none

Form 2

Syntax:	IFSIZExx	[ size ] GOTO [ label ]
Forms:	IFSIZE=	[ size ] GOTO [ label ]
	IFSIZE<	[ size ] GOTO [ label ]
	IFSIZE>	[ size ] GOTO [ label ]
	IFSIZE<=	[ size ] GOTO [ label ]
	IFSIZE>=	[ size ] GOTO [ label ]
	IFSIZE!=	[ size ] GOTO [ label ]
Arguments:	[ size ]	Variable, string, or numeric constant defining a numeric value to compare against the size of the file obtained with the most recently executed GETNEXTFILE, GETFILE, GETSITEFILE, or FTPGETFILE script command.
	[ label ]	A valid label within the current script file which is branched to if the date condition is satisfied.
Options:	none

Form 1 of this command is used in conjunction with the FILECOMPARETO and FILECOMPAREFROM script commands to test the results of a size comparison of a local file and a file on the FTP site.

Form 2 of this command is used in conjunction with the most recently executed GETNEXTFILE, GETFILE, GETSITEFILE, or FTPGETFILE command to compare the size of the file with a specified numeric value.

Description for Form 1

Possible result codes stored in %comparesize for the FILECOMPARETO command are listed below:

$ERROR_SRVR_FILE_LARGER	1226	File on server is larger
$ERROR_SRVR_FILE_SMALLER	1226	File on server is smaller
$ERROR_NO_SRVR_FILE_EXISTS	1228	File does not exist on server
$ERROR_SRVR_FILE_EMPTY	1229	File exists on server but its length is 0
$ERROR_FILES_SAME_SIZE	1234	Local and FTP site files identical in size

Possible result codes stored in %comparesize for the FILECOMPAREFROM command are listed below:

$ERROR_FILES_SAME_SIZE	1234	Local and FTP site files identical in size
$ERROR_LOCAL_FILE_LARGER	1235	Local file is larger
$ERROR_LOCAL_FILE_SMALLER	1236	Local file is smaller
$ERROR_NO_LOCAL_FILE_EXISTS	1239	Local file does not exist
$ERROR_LOCAL_FILE_EMPTY	1240	Local file exists but length equals 0

For example, the following conditional branch is taken if no file on the FTP site is found with the same name as a specified local file:

FILECOMPARETO "thatfile"

IFSIZE $ERROR_NO_SRVR_FILE_EXISTS GOTO no_file

Description for Form 2

The following conditional branch is taken if a local file just obtained with the GETNEXTFILE command has a size larger than 1000 bytes.

GETNEXTFILE "*.txt"

IFSIZE> 1000 GOTO good_file

Syntactically, no space is permitted to the left of the ‘!’, '=', '<' or '>' symbols, and a space is required to the right of these symbols.
