2. Decimal F o r m a t — a n u m b e r between -128.0000 a n d 127.9999 with
a n optional decimal point a n d decimal fraction with up to four
significant digits. If no sign is specified, the p a r a m e t e r is a s s u m e d to
be positive.
3. Label Fields — a n y combination of text, numeric expressions, or
string variables. Refer to T h e Label Instruction, LB, C h a p t e r 5, for a
complete description.
Some i n s t r u c t i o n s s u c h a s PA, PR, P U , a n d P D m a y h a v e multiple
p a r a m e t e r s . S e p a r a t o r s are required between these p a r a m e t e r s . These
optional parameters are shown in parentheses in the s y n t a x descriptions.
The s y n t a x s h o w n u n d e r t h e description of e a c h HP-GL instruction
