Increment

Revision as of 21:25, 8 April 2019 by Andrew Korson (talk | contribs) (Created page with "The '''increment''' command increases a variable's value by one. == Syntax == increment(var vA);<br /> ++vA;<br /> vA++;<br /> vA = vA + 1;<br /> v...")
The increment command increases a variable's value by one.
Syntax
increment(var vA);
++vA;
vA++;
vA = vA + 1;
vA += 1;
Remarks
Unlike the addn command, the increment command does not wrap around. If the value of vA is already 255, executing the increment command has no effect; the value will remain at 255.
When using the alternate syntax vA = vA + 1; WinAGI will compile an increment command. If you specifically want to use the addn command, you must use the full command syntax (addn(vA, 1);).
Possible Errors
None.
Example
Code:
<syntaxhighlight lang="agi"> v50 = 254; increment(v50); [ v50 now equals 255 ++v50; [ v50 still equals 255 v50 = v50 + 1; [ WinAGI compiles this as an increment command, so v50 still equals 255 addn(v50, 1); [ now v50 = 0 </syntaxhighlight>
