Symbols are defined by issuing the following command
SIC> SYMBOL TOTO "Whatever you want"
A symbol definition may refer to an other already defined symbol. Whenever
'TOTO' is found in a command line, it will be replaced by the string
Whatever you want e.g.
SIC> LABEL "Units 'TOTO'"
will be interpreted as
SIC> LABEL "Units Whatever you want"
The Symbol Table can be listed using command SYMBOL without arguments. If SYMBOL has a symbol name for argument, the translation of this symbol is given. DELETE /SYMBOL TOTO will delete symbol TOTO from the current symbol table. Note that symbols should only include alphanumeric characters.
