VVSETC(3NCARG)

💖 VVSETC 💖

okay so this is a page from the NCAR Graphics manual (that's the 3NCARG situation bestie, third section, NCAR Graphics family) and it's all about one lil' function that sets a Vectors parameter of type CHARACTER. she's giving very much "one job, does it well" energy and honestly? respect. 🫶

---

✨ NAME ✨

VVSETC — sets the value of a Vectors parameter of type CHARACTER. that's it, that's the whole gig, and she ate. 💅

---

✨ SYNOPSIS ✨

CALL VVSETC (CNM,CVL)

---

✨ C-BINDING SYNOPSIS ✨

#include <ncarg/ncargC.h>

void c_vvsetc (char *cnm, char *cvl)

---

✨ DESCRIPTION ✨

okay so here's the tea on the two arguments, listen up 🎀

• CNM (CHARACTER, input) — this is the name of the parameter you wanna give a character value to. only the first three characters of CNM are examined, which is lowkey unhinged but that's just how she is. those three characters gotta be either entirely upper case or entirely lower case — mixed case is not recognized, no cap, she will simply not see you. 💀 and the manual highly recommends you use the rest of the character string to make your code readable, like a little love note to future you. for example, instead of ZFT, use ZFT - Zero Field Text String. iconic behaviour, do that. ✨
• CVL (CHARACTER, input) — this is an expression, and its value is what gets handed over to the parameter that CNM named. so CNM picks the slot, CVL is the gift you're putting in it. 🎁

---

✨ C-BINDING DESCRIPTION ✨

the C-binding argument descriptions are the exact same as the FORTRAN argument descriptions. no notes, no changes, they're twins. 👯‍♀️

---

✨ USAGE ✨

this routine lets you set the current value of Vectors parameters of type CHARACTER. and if you want the full menu of every parameter available in this utility, go read the vectors_params man page — she has the whole list, go off queen. 📋

---

✨ EXAMPLES ✨

use the ncargex command to see these relevant examples, they're both real ones:

• fcover
• ffex00

go look at them, they're cute, they'll show you the vibe. 🌸

---

✨ ACCESS ✨

to use VVSETC or c_vvsetc, you gotta load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c — and preferably in that exact order. like, in that order fr fr, don't be chaotic about it. 🔥

---

✨ MESSAGES ✨

want the full rundown of every Vectors error message and/or informational message? that's all over on the vectors man page. she's got the receipts. 🧾

and that's the page bestie, you're officially VVSETC-pilled. 💖

okay and for the sign-off, this one's from the UNIX manual, dated April 1993 — yes she's an elder but she's still slaying, we love a vintage icon 🎀✨ bye bestie, go set some character parameters 💅🌈
