|Syntax||MORE [#ch,] filename|
|Location||MORE (DIY Toolkit - Vol V)|
This command adds a quite sophisticated file viewing facility to the QL which far surpasses the simple Toolkit II VIEW command.
In its simplest form, MORE will open a channel to the specified filename (adding the data default directory if the file does not exist) and display it in the specified window channel (default #1). If #ch does not refer to a window or is #0, then bad parameter will be reported. The file will then be displayed in the specified channel, one window full at a time. #0 is used by the command to display the length of the file in bytes and the number of the last byte displayed in the window.
You can move around the file by using the following keys:
- <ENTER> - Allows you to enter a file position to look at (this will be the first byte displayed in the window).
- <ALT><UP> - This moves back up the file one page at a time.
- <ALT><DOWN> - This moves down the file one page at a time.
- <DOWN> - Move down the file one line.
- <ESC> - Leave MORE.
MORE can however, also be used to look at the QL’s memory (or that on a networked computer) by using the MEM device. In this mode, only the address of the last byte on screen is shown in #0 - there is no file length. For example:
will allow you to use MORE to page through the whole of the QL’s memory.
allows you to page through the whole of another computer’s memory.
OPEN #3,MEM7_60p: PRINT #3,'Hello World': CLOSE #3
creates a permanent buffer (MEM7) and stores two words in it. If you follow the above by:
then you will be able to look at the contents of the buffer MEM7.
Trying to use MORE on anything other than files or MEM devices (for example on named pipes) will cause problems - press <CTRL><SPACE> a few times to escape from this.
Refer to the Devices Appendix for more details on MEM.
