Introduction
GRP is a package of QCL commands
for plotting purposes. A list of parameters can be associated with
these commands. The parameter list must be separated from the command
name by at least one space and each parameter is separated from its
neighbour by a comma. Literal strings should be enclosed in single
quotes although if the string is not an QCL symbolic name then the
literal string will be assumed even if no quotes are present. All the
available QCL operators can be used within the parameter list as
required. For example:
qcl>ZONE 1.0,0.0,YLIM+3,YMAX
qcl>TABLE './table.dat'
If the parameter list is shorter than required by the command then the
missing parameters will take their current values if they already
exist or will be prompted for if they don't. If it is required to use
the default value of a parameter then a dollar symbol can be used:
qcl>AMAP $,$,YMIN,YMAX
All the QCL parameters used by the GRP package are prefixed by GRP_ so
that they are easily handled as a group. To clear all the current GRP
parameters use the command:
qcl>.ERASE GRP_*
