char
specifies the control character being defined.
VAriable
defines a REXX variable identifier control character. Variable identifier control characters are used to associate Panel Facility control characters with REXX variable names. More than one variable control character can be defined at one time. Following the VARIABLE keyword may be a list of variable names (variable) or a single stem name (stem.). The variable list can contain one to 32,767 variable names. Only one stem name can be specified and the stem name must end in a period. This period identifies the variable as a stem and leaving off the period causes the name to be interpreted as a simple variable.

Using a variable list and a stem name cannot be mixed. When the panel generator encounters a variable control character a substitution is done. Simple variable lists are substituted in the same order as listed. For example, the third variable control character is replaced with the third variable listed for that control character. The stem variable is replaced by appending a three-character number (tail) to the stem name. The number starts at 1 and is incremented as that stem control character is encountered. Therefore, the tenth stem control character for a particular stem would have a 10 as the tail (STEM.10). Since these variables are REXX variables, they must follow the REXX variable naming rules.

DROP
drops char as a field control character.
