8.48 DEFSYM (Define a symbol)

8.48.1 Function

The DEFSYM command defines symbol ‘symbol’ as to contain value ‘value’. The symbol can then be the
object of a substitution for later panel commands. If the value contains blanks or spaces then it must be
enclosed within quotes or apostrophes. See chapter “Symbol Substitutions” for a more in-depth discus-
sion on this feature.
