Description
as the character type. It defines the type of all variables starting with a character specified
by <alphabetical character> or with a character within the range specified by <alphabetical
character-alphabetical character> as the character type.
• Specification by the type declaration statement has priority for specifying the variable type,
and the result will be as follows:
Example
• Variables defined as character type by the DEFSTR instruction and variables with the
character type declaration character '$' are regarded as the same.
Example
• If the type is not declared by the DEFSTR instruction, a variable that has a variable name
without type declaration character is regarded as a single precision variable.
