MAXTAB returns the highest version number of specific table type
attached to a file. This information is often needed when writing loops
to automate operations in POPS. For example you can print out antenna
tables for all of the subarrays belonging to a data file using the
following loop.
MAXTAB is defined in several RUN files. You must have RUN one of
VLBAUTIL, VLAPROCS, DOVLAMP, or VLBAARCH to get the definition.
DOCRT = FALSE
NPRINT = 0
FOR INVER = 1 TO MAXTAB('AN') ; RUNWAIT ('PRTAN'); END
MAXTAB operates on the file specified using the USERID, INFILE, INCLASS,
INSEQ, and INDISK adverbs. If this file has no files of the specified
type then MAXTAB will return a value of zero.
