A SETPRT macro instruction was issued for a 3800 printer. The character arrangement table module cannot be loaded. The number of unique character sets it specified, when combined with the number of unique character sets specified by other character arrangement tables, would require more writable character generation modules (WCGMs) than are available. The number of WCGMs on the printer is 2 or 4, as indicated in the message text.

When two or more character arrangement tables specify the same character set, only one copy of that character set is loaded into a WCGM. However, if a character arrangement table calls for graphic modification modules for a character set, the modified character set is considered unique.
