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 "GO verb_name" is converted by AIPS to "TPUT verb_name ; verb_name" which saves the adverbs of "verb_name" for a later TGET and then executes "verb_name". The syntax "TASK = ’verb_name’ ; GO" will not work. **************************************************************** ABOUT displays lists and information on tasks, verbs, adverbs ABS returns absolute value of argument ACOS Returns arc cosine of argument (half-circle) ACTNOISE puts estimate of actual image uncertainty and zero in header ADDBEAM Inserts clean beam parameters in image header ALLDEST Delete a group or all of a users data files ALTDEF Sets frequency vs velocity relationship into image header ALTSWTCH Switches between frequency and velocity in image header APROPOS displays all help 1-line summaries containing specified words ASIN Returns arc sine of argument (half-circle) ATAN2 Returns arc tangent of two arguments (full circle) ATAN Returns arc tangent of argument (half-circle) AVEOT Advances tape to end-of-information point AVFILE Moves tape forward or back to end-of-file marks AVMAP Advance tape by one image (IBM-CV = obsolete tape file) AXDEFINE Define or modify an image axis description BAMODIFY edits characters in a line of a batch work file BATCH starts entry of commands into batch-job work file BATCLEAR removes all text from a batch work file BATEDIT starts an edit (replace, insert) session on a batch work file BATLIST lists the contents of a batch work file BY gives increment to use in FOR loops in POPS language CALDIR lists calibrator models available as AIPS FITS files CATALOG list one or more entries in the user’s data directory CEIL returns smallest integer greater than or equal the argument CELGAL switches header between celestial and galactic coordinates CHAR converts number to character string CHKNAME Checks for existence of the specified image name CLR2NAME clears adverbs specifying the second input image CLR3NAME clears adverbs specifying the third input image CLR4NAME clears adverbs specifying the fourth input image CLRMSG deletes messages from the user’s message file CLRNAME clears adverbs specifying the first input image CLRONAME clears adverbs specifying the first output image CLRSTAT remove any read or write status flags on a directory entry CLRTEMP clears the temporary literal area during a procedure COODEFIN Define or modify an image axis coordinate description COPIXEL Convert between physical and pixel coordinate values COS returns cosine of the argument in degrees COSTAR Verb to plot a symbol at given position on top of a TV image COWINDOW Set a window based on coordinates CPUTIME displays curren tcpu and real time usage of the AIPS task CURBLINK switch TV cursor between steady and blinking displays CURVALUE displays image intensities selected via the TV cursor DEFAULT Verb-like sets adverbs for a task or verb to initial values DELBOX Verb to delet boxes with TV cursor & graphics display.
