Memo Pad is named after the memo pad found on the Atari 400 and 800 computers. Memo Pad allows you to view and edit ASCII and ATASCII files. It displays the files using the same fonts used on the Atari 400, 800, XL, XE and ST computers.
March 30, 2020:
It has been a while but Memo Pad is still being developed. Release 27 is coming soon. Tab characters will finally be handled properly. They will be rendered as a user specified number of spaces and converted between ASCII and ATASCII. I'm hoping to also finish adding Replace to the current Find but that may have to wait for 28.
Release 19 and later runs under Wine.
The following shows Memo Pad running under Wine 2.0 on Ubuntu 16.04.

Enable Control Graphics to enter the Atari graphic characters. When enabled you press and hold a control key and then press a letter or symbol key. The 26 letters give the same graphic character as typing on a real Atari 8-Bit computer. The remaining 3 graphic characters use 3 symbol keys. These keys are different than a real Atari 8-Bit computer. See the image below for the mapping of all 29 graphic characters.
When using Control Graphics please beware of the following:
The image below shows how to search for the word "assembly". Normally you would simply choose Text and enter "assembly" then click a Find button. For demonstration purposes the image shows the word broken into pieces. This is done to demonstrate Escape Sequences when finding by text and demonstrates the different value notations when finding by value.
Find Text allows you to search your file for a string of characters. A string of characters can be any character you can type into the edit box and even characters you can not type if you enable Escape Sequences.
The following table lists the supported Escape Sequences.
|\'||single quote||39 0x27|
|\"||double quote||34 0x22|
|\?||question mark||63 0x3F|
|\f||form feed / new page||12 0x0C|
|\n||line feed / new line||10 0x0A|
|\r||carriage return||13 0x0D|
|\t||horizontal tab||9 0x09|
|\v||vertical tab||11 0x0B|
|\???||1 to 3 digit decimal value|
|\0???||1 to 3 digit octal value|
|\x??||1 or 2 digit hexadecimal value|
Find Value allows you to search your file for a single byte value or a sequence of byte values. Values can be specified in decimal, hexadecimal, and octal notation. There is also a single character notation for those times you don't recall the ASCII value of a character. When entering multiple values you may need to put a space between them to avoid collisions.
And for completeness you can put between double quotes everything supported with Find Text. Why not?
The following table lists the supported notations.
|???||1 to 3 digit decimal value|
|0???||1 to 3 digit octal value|
|0x??||1 or 2 digit hexadecimal value|
|$??||1 or 2 digit hexadecimal value|
|"?..."||1 or more characters.|
Escape Sequences supported.
