(l) Load a file.

• Type l then return to load a file. Then, you can give its full name with extension name, e.g. ``fileName.ocw''. All *nix systems except Mac OS X are case sensitive.
• alternatively, you may type only ``fileName'': if this file doesn't exist, the program will try to open first fileName.ocw and will then look for extensions .OCW, .dat, .DAT, .oew, .OEW, .oxw and .OXW...(anything else added upon request.)
• The data files in the directory are listed on screen ; you can therefore use the mouse to copy (left button) and paste (middle button) the name of the file you want to load.
• You may also simply type l filename (the argument after l is taken as the finename). You can use the TAB key for automatic completion.

Whatever your choice, extra blank(s), before and/or after the file name, don't matter.

The maximum number of points allowed in a scan is set to 8192; the following data points are ignored. I agree, that's not very clever, but that could be fixed if you've got huge files. (Note that scanning over one volt and back, making steps of 1mV, results in a file containing only 2000 E/i values, so the upper limit for the number of data points should not be a real problem.)

For the ``Load'' and ``oVerlay'' commands, if you change your mind and don't want to load/overlay any more, just type return. This is the meaning of the ``filename ([return to abort]) :'' written on the screen when you are asked for a filename.

See also the ln command to load SWV (.oew) files, and loadstack to load a stack.

Using GreG to load a file in an arbitrary (ascii) format.

1. enter GreG from soas typing g,
2. type something like col x 7 y 12 /file filename /lines 34 1000
   to read from the file filename the 7th column as X, the 12th as Y, starting at line 34, ending line 1000
   If filename contains capitalized letters, type /file "!fIlEnAmE" instead of /file fIlEnAmE
3. exit GreG typing q, and answer y (default) to the question Update buffer ([y]/z/n) ?.
