Plotchar - Allows a user to draw characters of high, medium, or low quality.
PCHIQU (or PLCHHQ) - Draws high quality characters. By default, it uses the same database as the old NCAR Graphics routine PWRITX, but it can also use characters from any of the fontcap-defined databases, it has an improved interface, and it has many more capabilities than PWRITX. PCMEQU (or PLCHMQ) - Draws characters of "medium quality". It does this by drawing lines, just as PCHIQU does, but it does not produce quite such fancy characters. No function codes may be used. Using PCMEQU to draw a given string of characters will create a larger metafile than if PCLOQU were used, which may be a disadvantage. However, it may also be more dependable, in that it does not depend on capabilities the translator may or may not have. PCLOQU (or PLCHLQ) - Draws characters of "low quality" by calling the GKS character- drawing routines. No function codes may be used. Using PCLOQU to draw a given string of characters will create a smaller metafile than if PCHIQU or PCMEQU were used; the results will depend on capabilities of the translator. PCGETC - Retrieves the character value of a specified internal parameter. PCGETI - Retrieves the integer value of a specified internal parameter. PCGETR - Retrieves the real value of a specified internal parameter. PCRSET - Resets the values of all internal parameters to the default state. PCSETC - Gives a new character value to a specified internal parameter. PCSETI - Gives a new integer value to a specified internal parameter. PCSETR - Gives a new real value to a specified internal parameter. PCPNWI - A function of type CHARACTER*16 that, given the name of an internal parameter array and an index, has as its value the name of the specified element of the internal parameter array. PCDLSC - Defines the default list of "special colors" used by PCHIQU in drawing certain characters from the filled fonts. Such a call will define color indices IFCI, IFCI+1, IFCI+2, . . . , IFCI+15 and it will set all elements of the internal parameter array ´CC´ corresponding to indices 1 through 16. At the moment, although such a call does define a set of sixteen colors (ranging from blue to red) and set the elements of ´CC´, it´s a bit pointless, since there are no characters for which the special colors are used. In the future, there will be a few such (like the state highway symbol, which is normally drawn in a particular pair of colors); at that time, the routine will be of more use. PLCHHQ - An alternate name for the routine PCHIQU. PLCHMQ - An alternate name for the routine PCMEQU. PLCHLQ - An alternate name for the routine PCLOQU.

USER-MODIFIABLE INTERNAL ROUTINES
PCMPXY - This routine is normally not called directly by the user (though it can be). It is called by PCHIQU and by PCMEQU when the user has set the mapping flag ´MA´ nonzero to request mapping of characters from one X/Y coordinate system to another.
To use Plotchar routines, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
Various error conditions can occur in Plotchar. Each of these results in a call to the error-handling routine SETER, with a final argument indicating that the error is recoverable; by default, an error message is printed and execution is terminated, but, if you turn on error recovery (as described in the "man" page for "error_handling"), you can get control back. The error messages are as follows; all should be more or less self-explanatory. PCDLSC - FIRST COLOR INDEX IS LESS THAN ZERO PCDLSC - UNCLEARED PRIOR ERROR PCGETC - UNCLEARED PRIOR ERROR PCGETC - UNRECOGNIZED PARAMETER NAME PCGETI - UNCLEARED PRIOR ERROR PCGETR - BOX COLOR ARRAY INDEX IS OUT OF RANGE PCGETR - COLOR ARRAY INDEX IS OUT OF RANGE PCGETR - UNCLEARED PRIOR ERROR PCGETR - UNRECOGNIZED PARAMETER NAME PCHIQU - UNCLEARED PRIOR ERROR PCLOQU - UNCLEARED PRIOR ERROR PCMEQU - UNCLEARED PRIOR ERROR PCPNWI - INTERNAL ERROR - SEE CONSULTANT PCPNWI - PARAMETER NAME TOO SHORT PCSETC - UNCLEARED PRIOR ERROR PCSETC - UNRECOGNIZED FONT NAME PCSETC - UNRECOGNIZED PARAMETER NAME PCSETI - UNCLEARED PRIOR ERROR PCSETR - BOX COLOR ARRAY INDEX IS OUT OF RANGE PCSETR - COLOR ARRAY INDEX IS OUT OF RANGE PCSETR - UNCLEARED PRIOR ERROR PCSETR - UNRECOGNIZED PARAMETER NAME PLCHHQ - DATASET NOT LOADED CORRECTLY PLCHHQ - ERROR EXIT FROM GQCNTN PLCHHQ - ERROR EXIT FROM GQFACI PLCHHQ - ERROR EXIT FROM GQFAIS PLCHHQ - ERROR EXIT FROM GQLWSC PLCHHQ - ERROR EXIT FROM GQNT PLCHHQ - ERROR EXIT FROM GQPLCI PLCHHQ - ERROR EXIT FROM GQTXCI PLCHHQ - INTERNAL LOGIC ERROR (NCRA TOO BIG) - SEE CONSULTANT PLCHHQ - INTERNAL LOGIC ERROR (NDGU = 0) - SEE CONSULTANT PLCHHQ - INTERNAL LOGIC ERROR (NPCS TOO BIG) - SEE CONSULTANT PLCHHQ - INTERNAL LOGIC ERROR (XCP1 OR XCP2 = OORV) - SEE CONSULTANT PLCHHQ - INTERNAL LOGIC ERROR (XCRA/YCRA TOO SMALL) - SEE CONSULTANT PLCHHQ - UNCLEARED PRIOR ERROR PLCHLQ - ERROR EXIT FROM GQCHH PLCHLQ - ERROR EXIT FROM GQCHUP PLCHLQ - ERROR EXIT FROM GQCNTN PLCHLQ - ERROR EXIT FROM GQNT PLCHLQ - ERROR EXIT FROM GQTXAL PLCHLQ - ERROR EXIT FROM GQTXP PLCHLQ - UNCLEARED PRIOR ERROR PLCHMQ - UNCLEARED PRIOR ERROR
