SIC allows the user to define symbols, which are abbreviations of any character string. Any command line is first parsed for symbols in the symbol table. The command interpretor assumes that the following entities may be symbols :
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.
