4.38 - [vinc] Built-In

Mnemonic aid: vinc for Variable INCrement

See also:  [gload] ,  [global] ,  [graw] ,  [gsave] ,  [gv] ,  [load] ,  [local] ,  [lv] ,  [page] ,  [raw] ,  [save] ,  [v]  and  [vdec] 

 [vinc]  increments a variable. If quiet=1 is provided, then it will not generate any content. If pre=1, then it will produce the value of the variable before the increment. Otherwise it produces the value of the variable after the increment.

 [vinc]  prefers a local variable, but if a local does not exist, then it will increment a global if that exists.
