ASPL symbolic operators can be typed on a terminal by using any standard keyboard that can emit the 95 printable characters in the ASCII standard code page. They include letters, numbers, symbols, and punctuation marks, and are represented by codes 32 to 126. These characters can be typed directly on your keyboard to create written text and other visual content on your display. All ASPL symbolic operators can be typed directly by using any basic keyboard. No special symbols are used in any ASPL operator or command.

At any time you can use the command asplsymbols to print the symbolic operators. For example, at the shell prompt enter this command:

#  asplsymbols -tickphrase setops

to display the table showing the setops. To display the xsetops (transform set operators), you will enter:

#  asplsymbols -tickphrase xsetops

and to display the seqops (sequence alignment set operators), you will enter:

#  asplsymbols -tickphrase seqops2

You can also look at the tick predicates associated with a specific symbolic operator. To look at the checksum intersection c&, you will enter:

#  asplsymbols -ticksymbol 'c&'

You can display the symbolic operators per category. The following are the know categories: setops, xsetops, asetops, seqops2, seqops3u, seqops3i, seqops3d, prod1, prod2.
For example to display the symbols under setops category, you will enter the following command:

#  asplsymbols -phrase setops

To display the basic operators under prod1 category:

#  asplsymbols -phrase prod1

To display the basic operators under prod2 category:

#  asplsymbols -phrase prod2

The following grid shows the symbolic operators, with the exception of ASPL differential group operators (which are discussed separatly in their own chapter). Refer to the chapter Differential Group Operations for information on ASPL differential group operators.
