1.1 Variables
Syntax (DEF...=SET...)
Using a value list:
• During definition:
DEF <data type> <variable
name>[<n>,<m>,<o>]=SET(<value1>,<value2>, etc.)
Equivalent to:
DEF <data type> <variable name>[<n>,<m>,<o>]=(<value1>,<value2>,
etc.)
Note
SET does not have to be specified for initialization via a value list.
• During value assignment:
<variable name>[<n>,<m>,<o>]=SET(<VALUE1>,<value2>, etc.)
Syntax (DEF...=REP...)
Using a value with repetition
• During definition:
DEF <data type> <variable name>[<n>,<m>,<o>]=REP(<value>)
DEF <data type> <variable name>[<n>,<m>,<o>]=REP(<value>,
<number_array_elements>)
• During value assignment:
<variable name>[<n>,<m>,<o>]=REP(<value>)
DEF <data type> <variable
name>[<n>,<m>,<o>]=REP(<value>,<number_array_elements>)
Significance
DEF:
<data type>:
<string length>:
