MAPFST(3NCARG)

💖 MAPFST — bestie, it's pen-moving time 💖

NCAR Graphics manual, section 3NCARG. Yes this is the MAPFST(3NCARG) page. Sit down, hydrate, and let's draw some lines on a map ✨

---

✨ NAME ✨

MAPFST — draws lines on a map, and it's meant to be used in conjunction with MAPVEC. They're a duo, fr fr 🫶

---

🌸 SYNOPSIS 🌸

CALL MAPFST (RLAT,RLON)

---

🦋 C-BINDING SYNOPSIS 🦋

#include <ncarg/ncargC.h>

void c_mapfst (float rlat, float rlon)

---

👑 DESCRIPTION 👑

• RLAT and RLON — these are input expressions, of type REAL, and they specify the latitude and longitude of a point that the "pen" is gonna be moved to. Both are in degrees, okay? And listen: RLAT has to be between -90. and +90., inclusive, and RLON has to be between -540. and +540., inclusive. That's the range, no cap 💅

---

🎀 C-BINDING DESCRIPTION 🎀

The C-binding argument descriptions are literally the same as the FORTRAN argument descriptions. Same energy, different syntax 🧚

---

🔥 USAGE 🔥

So this statement:

CALL MAPFST (RLAT, RLON)

is equivalent to:

CALL MAPIT (RLAT, RLON, 0)

What it does: it moves the "pen" — and the pen is in the "up" position the whole time, okay, so we're not drawing, we're traveling — to the first point in a series of points. Like, you're getting your pen into position before the real work starts. Main character setup moment ✨

Go read the man page for MAPIT too, bestie, it's giving the full lore.

🌈 ACCESS 🌈

To use MAPFST or c_mapfst, you gotta load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c — and preferably in that order, don't fight the order, the order ate 💯

Okay that's the whole page, you ate that 🎀 This was the MAPFST(3NCARG) page from the NCAR Graphics manual, source is UNIX, dated March 1993 — yes she's an elder but she still slays 💅✨
