(Ghostscript Errors) header
(PostScript operates by maintaining several) jnl
(stacks, on which various objects are placed) jnl
(and operated on. When an error occurs,) jnl
(Ghostscript will print an error message and) jnl
(will display the contents of its stacks in) jnl
(the console window. This stack dump is) jnl
(sometimes difficult to interpret, and the) jnl
(source of the error may not be clear.) jnl
(Generally, the name of the error that) jnl
(occured and the contents of the operand) jnl
(stack are most useful in decoding the error) jnl
(message.) jnl
return
(After an error occurs, the prompt may) jnl
(change to look something like GS<3>. This) jnl
(means that there are now three objects) jnl
(remaining on the operand stack. Typing) jnl
("clear" or typing "pop" three times will) jnl
(clear the stack. Typing "==" will display) jnl
(the object on the top of the stack.) jnl
return
(Some common errors are:) jnl
return
(/undefinedfilename in --file--) jnl
(GS could not open the file whose name is on) jnl
(the operand stack. If the file name begins) jnl
(with gs_, it is a startup file required by) jnl
(GS. Check the GS_LIB environment variable) jnl
(\(see the files "use.doc" and "readme.st"\).) jnl
return
(/undefined in somename) jnl
(GS has encountered a procedure or variable) jnl
("somename", which has not been defined.) jnl
(Often this is the result of a missing) jnl
(header file which should be run before the) jnl
(offending file.) jnl
return
(/rangecheck in --somename--) jnl
(The procedure "somename" was passed a bad) jnl
(value as an argument. For example, passing) jnl
(a negative number to the sqrt operator will) jnl
(result in a rangecheck error. The offending) jnl
(argument should be on the operand stack.) jnl
return
(/typecheck in --somename--) jnl
(The procedure "somename" was passed a) jnl
(parameter of the wrong type. For example,) jnl
(passing a string to the add operator will) jnl
(result in a typecheck error. The offending) jnl
(argument should be on the operand stack.) jnl
return
(/VMerror) jnl
(Ghostscript has run out of memory. Try) jnl
(reducing the resolution of the image.) jnl
