Type:  General type of POPS symbol  
Use:   Pseudo-verbs are magic symbols which cause FORTRAN routines to  
       carry out specific actions.  Unlike verbs, pseudo-verbs are  
       executed as soon as they are encountered by the compiler even  
       in compile mode.  In general, the FORTRAN routines which are  
       invoked will parse the remainder of the input line under  
       special, non-standard rules.  Any normal code typed on the line  
       ahead of the pseudo-verb will not be executed.  
Grammar:  See the \zxhlp{HELP} listings for the specific pseudoverb.  
Examples:    \zxhlp{HELP}  \zxhlp{HELP}  
             \zxhlp{ARRAY}   JUNK(4, -7 \zxhlp{TO} 9)  
             \zxhlp{PROC} DUMMY (I,J)  
             \zxhlp{LIST} DUMMY  
             \zxhlp{DEBUG} \zxhlp{TRUE}  
             \zxhlp{INPUTS} MLOAD
