13.40 VERB

\zxhlp{VERB}  
Type:  General type of POPS symbol  
Use:   Verbs are the magic words which cause FORTRAN code to  
       execute some function.  They are compiled into AIPS  
       by the programmers and their meaning remains fixed  
       at least until the programmers change their minds.  
Grammar:   Verbs may be given either in compile mode or in  
       regular execute mode.  In the former, their pointers  
       are stored with the procedure and they are executed  
       when the procedure is invoked.  In the latter, they  
       are compiled with the other statements and parameters  
       on the input line and then executed before a new  
       input line is read.  
Execution:  Verbs are executed when the line in which they  
       appear is executed and are simply referenced by their  
       name.  The syntax "\zxhlp{GO} verb_name" is converted by AIPS to  
       "\zxhlp{TPUT} verb_name ; verb_name" which saves the adverbs of  
       "verb_name" for a later \zxhlp{TGET} and then executes  
       "verb_name".  The syntax "\zxhlp{TASK} = ’verb_name’ ; \zxhlp{GO}" will  
       not work.
