GetString

GetString $variable,filename,line#[,label:]

Where:

$variable

receives the text read from the file.

filename

is the full filename, including drive letter and path name for the input file. This file must be a text file. Enclose the filename in double quotation marks ("") if it contains embedded spaces or commas.

line#

is the line number of the line to be read from the input file.

label

is the label of an error handler routine. The script branches to this routine if the I/O fails. The I/O error handler routine can use the $FILESTAT variable to get the cause of the error. If this parameter is omitted, the user will be prompted with the script error dialog box which allows the command to be retried or ignored.

filename and line# may be variables.

The GetString command reads a line of text from a file and copies it into a script variable.
