SUBROUTINE SYMEX (TEXT,ISTART,LENTXT,WCLEN) C$ (String Extent) C$ Find plotted length of a text string. The current C$ orientation and size attributes for text are assumed. The C$ current point determines the location where the text is C$ drawn, and is unchanged on return. The string then C$ terminates at the point (Current Point) + WCLEN*(Path Unit C$ Vector), assuming default string justification. This C$ information may be useful for concatenation of successive C$ text strings. The arguments are: C$ C$ TEXT(*).....INTEGER array or Hollerith string defining C$ characters to be plotted. C$ ISTART......Index of starting character in TEXT(*), C$ counting from 1 from the left. If LENTXT .LT. C$ 0, this indicates that symbol numbers begin in C$ TEXT(ISTART). C$ LENTXT......Number of characters in TEXT(*) to plot. If C$ LENTXT .GT. 0, TEXT(*) contains packed C$ Hollerith characters. If LENTXT .LT. 0, then C$ TEXT(*) contains IABS(LENTXT) Hershey symbol C$ numbers (one/word) defining the characters to C$ be plotted. only the first "MAXSYM" (=150) C$ characters will be plotted if a packed string C$ is passed. This restriction arises from the C$ dimension of NUMSYM(*) below, and may be easily C$ changed if required. C$ WCLEN.......Length of string in world coordinate units. C$ C$ (29-JAN-83)
