Using spaces
One or more spaces must be used in a model statement to separate the name, operation,
operand, and remarks fields from each other. Spaces cannot be generated between fields in order to
create a complete assembler language statement. The exception to this rule is that a combined
operand-remarks field can be generated with one or more spaces to separate the two fields.
Note: If
the generated operand field is part of a macro instruction, the entire string (including spaces) is
passed as an operand.
